Jupiter 2019

The GRS wake has a fresh rift.

UTC

A mixed night for planetary imaging. While seeing was very good, it was quite breezy, a weak point for the CGEM DX when the C14 with imaging equipment is saddled on it. To take advantage of the night, I used the C8 instead.

Notes:

  • White Oval Z is about to set.
  • The SEBn trailing the GRS is bright.
  • The Great Red Spot well past the central meridian.
  • The GRS wake appears to have a new rift suggested by its bright appearance.

More Info...
The northern South Equatorial Belt is lightened.

UTC

Notes:

  • White Oval Z is approaching the eastern limb.
  • The GRS is past the central meridian.
  • The SEBn is lighter than normal.
  • The SEBs following the GRS wake appears dark and clumpy.
  • To the east of the GRS, the darkened STZ has wave-like extensions reaching south.

More Info...

UTC

A mixed night for planetary imaging. While seeing was very good, it was quite breezy, a weak point for the CGEM DX when the C14 with imaging equipment is saddled on it. To take advantage of the night, I used the C8 instead.

Notes:

  • White Oval Z is about halfway between the central meridian and the eastern limb.
  • The EZ is still orange.
  • The GRS is past the central meridian.
  • The SEBn is almost white.
  • The SEBs following the GRS wake appears dark and clumpy.
  • The GRS hollow is dark.
  • To the east of the GRS, the darkened STZ has wave-like extensions reaching south.

More Info...
A dark hot spot in the Equatorial Zone is setting.

UTC

Seeing remained good during the CH4 capture. Clouds started coming in from the south near the end of the capture, causing me to rush for Saturn before it was too late to capture it.

Notes:

  • White Oval Z is east of the central meridian.
  • A dark hot spot in the Equatorial Zone is setting.
  • The Great Red Spot is just past the central meridian.

More Info...
The northern edge of the GRS appears to be touching the small storm embedded in the GRS hollow, which is not the case in the RGB image.

UTC

Seeing seemed to improve a bit, which helped the near-infrared filter that already cuts through seeing better than RGB filters.

Notes:

  • White Oval Z is east of the central meridian.
  • The Great Red Spot is at the central meridian.
  • A small storm is on the northern edge of the darkened GRS hollow.
  • The northern edge of the GRS appears to be touching the small storm embedded in the GRS hollow, which is not the case in the RGB image.
  • Dark clouds from the GRS hollow appear to be entering the South Tropical Zone, with a wavy pattern on the southern edge.

More Info...

UTC

Despite the threat of clouds appearing soon in the weather forecast, we decided it was worth trying to beat them for an image. Turned out to be a good decision because seeing was quite good.

Notes:

  • White Oval Z has just passed the central meridian.
  • Most of the Equatorial Zone is still orange
  • The northern regions of the South Equatorial Belt are light in color.
  • The Great Red Spot is at the central meridian.
  • A small storm is on the northern edge of the darkened GRS hollow.
  • Dark clouds from the GRS hollow appear to be entering the South Tropical Zone, with a wavy pattern on the southern edge.

More Info...
A prominent hot spot on the northern edge of the Equatorial Zone is at the central meridian.

UTC

Clouds started to show up after capturing tonight's near infrared image, but I still had enough time to capture a methane image.

Notes:

  • A prominent hot spot on the northern edge of the Equatorial Zone is at the central meridian.
  • The southern edge of the South Equatorial Belt is dark.
  • Oval BA is rising.
  • The South Polar Red Spot has passed the central meridian.

More Info...
A long rift on the North Equatorial Belt is approaching the central meridian.

UTC

The sky continued to defy an unfavorable forecast, so I hastily captured a near infrared image before it ended.

Notes:

  • A long rift on the North Equatorial Belt is approaching the central meridian.
  • The southern South Equatorial Belt is very dark.
  • Oval BA is rising.
  • The faint streak in the South Temperate I noted on an image from June 2 is at the central meridian.
  • The South Polar Red Spot is just east of the CM.

More Info...
The faint streak in the South Temperate I noted on an image from June 2 is at the central meridian.

UTC

Another night where the weather was more generous than the forecast suggested.

Notes:

  • The southern South Equatorial Belt is very dark.
  • Oval BA is rising.
  • The faint streak in the South Temperate I noted on an image from June 2 is at the central meridian.
  • The South Polar Red Spot is just east of the central meridian.
  • Io and Ganymede are approaching transit.

More Info...
The Great Red Spot is rising.

UTC

Peeking at the sky gave me the impression of having a potentially good imaging session, but a thick deck of clouds began covering the sky just before I started recording with my ASI290MM. To avoid being cut off from capturing a full color image, I quickly ran inside to get my ASI224MC. The sky around Jupiter was nearly opaque by the time I started recording.

Notes:

  • The Great Red Spot is rising.
  • Ganymede is about to transit over high northern latitudes.
  • Io has just left transiting the planet.

More Info...
The southern edge of the Equatorial Zone is darker than the rest of the zone.

UTC

I finally capped off the imaging session with another image through the methane filter.

Notes:

  • The southern edge of the Equatorial Zone is darker than the rest of the zone.
  • Oval BA is rising.

More Info...
A barge at mid-northern latitude appears more prominent in near infrared compared to visible light.

UTC

I continued tonight's second round of Jupiter imaging with the near infrared filter.

Notes:

  • A barge at mid-northern latitude appears more prominent in near infrared compared to visible light.
  • A bright outbreak in the North Equatorial Belt is approaching the CM.
  • Oval BA is rising.

More Info...
A bright outbreak is east of the central meridian.

UTC

After imaging Saturn, I decided to return to Jupiter to capture more images, something I hardly do. I found improved seeing conditions upon my return.

Notes:

  • A bright outbreak on the North Equatorial Belt is east of the central meridian.
  • The Equatorial Zone is orange, except the southern edge.
  • Oval BA is rising.
  • The South Polar Red Spot is near the CM.

More Info...
There is a bright spot on the central meridian at mid-northern latitudes. As far as I can tell, this spot is almost indistinguishable in visible light.

UTC

To round out Jupiter imaging for the night, I decided to capture a methane image to reveal the altitude of clouds.

Notes:

  • There is a bright spot on the central meridian at mid-northern latitudes. As far as I can tell, this spot is almost indistinguishable in visible light and faintly outlined in deep-red/infrared.
  • The southern edge of the Equatorial Zone is darker than the rest.
  • The South Equatorial Belt is split by a zone.

More Info...
The Equatorial Zone, unusually orange in visible light, appears normal in this wavelength.

UTC

After capturing some RGB sets, I decided to catch some deep-red/infrared photons from Jupiter.

Notes:

  • The Equatorial Zone, unusually orange in visible light, appears normal in this wavelength.
  • The northern South Equatorial Belt is lighter than normal.
  • The SEBs appears dark and clumpy.
  • Io is approaching Jupiter from the right.

More Info...

Seeing continued its crisp but turbulent nature.

Notes:

  • The Equatorial Zone, excluding its southern edge, is orange.
  • The northern South Equatorial Belt is lighter than normal.
  • The SEBs appears dark and clumpy.
  • Io is approaching Jupiter from the right.

More Info...
The SEBs appears dark and clumpy.

UTC

The first image of another June night with crisp but turbulent seeing and passable transparency. I've been seeing an unusually high number of rabbits in the yard this year, and there was one wondering around while imaging.

Notes:

  • The Equatorial Zone, excluding its southern edge, is orange.
  • The northern South Equatorial Belt is lighter than normal.
  • The SEBs appears dark and clumpy.
  • Io is approaching Jupiter from the right.

More Info...
The souther South Equatorial Belt is dark and clumpy.

UTC

I decided to stick with Jupiter for one more RGB capture of Jupiter after capturing IR data. I kept using the imaging train usually attached to the C14.

Notes:

  • The Equatorial Zone is orange.
  • The Great Red Spot is setting.
  • The GRS hollow is unusually dark.
  • The SEBs is dark and clumpy.
  • Io and Europa appear left and right of the planet respectively.

More Info...
The northern South Equatorial Belt has become is lighter than usual.

UTC

Seeing was still good despite the slow turbulence blurring smaller features. The grass started dewing up, but the C8's corrector stayed clear.

Notes:

  • White Oval Z is setting.
  • The northern South Equatorial Belt has become is lighter than usual.
  • The Great Red Spot is setting.
  • The SEBs is dark and clumpy.
  • Io and Europa appear left and right of the planet respectively.

More Info...
The South Equatorial Belt is split by a zone, which angles down towards the Great Red Spot.

UTC

Once I was done capturing for the RGB filter comparison, I moved on to filters I only have in the C14 imaging train, starting with the methane filter to show elevation of surface features.

Notes:

  • The South Equatorial Belt is split by a zone, which angles down towards the Great Red Spot.
  • Io and Europa appear left and right of the planet respectively.

More Info...
White Oval Z is setting.

UTC

After taking an image with my usual C8 imaging train with ZWO filters, I swapped it out for the C14 train with Chroma filters. Seeing was still turbulent but slow enough to see a decent amount of details.

Notes:

  • White Oval Z is setting.
  • The Equatorial Zone is orange.
  • The Great Red Spot is off-center in its hollow.
  • The GRS hollow is unusually dark.
  • South Equatorial Belt clouds are circulating around the GRS and into the South Tropical Zone to the east.
  • The SEBs is dark and clumpy.
  • Io and Europa appear left and right of the planet respectively.

More Info...
The Great Red Spot is off-center in its hollow.

UTC

I decided to setup the C8 even though I wasn't convinced in the moment the sky conditions would be good. The live view was turbulent, but slower than I'm used to seeing. I had both my imaging trains in the same place, so I decided to do a comparison between my ZWO filters for the C8 and my Chroma filters used with the C11 and C14. This image was done through the ZWO filters, while next image will be with the Chroma filters.

Notes:

  • White Oval Z is faintly visible on the North Equatorial Belt, north of the Great Red Spot.
  • The Equatorial Zone is orange.
  • The GRS is off-center in its hollow.
  • The GRS hollow is unusually dark.
  • South Equatorial Belt clouds are circulating around the GRS and into the South Tropical Zone to the east.
  • The SEBs is dark and clumpy.
  • Io and Europa appear left and right of the planet respectively.

More Info...
Clouds from the South Equatorial Belt are circulating around the GRS and into the South Tropical Zone to the east.

UTC

Another night starting with a test of the sky conditions with the 90mm Mak before bringing out a bigger scope. Conditions were not as good as the previous session.

Notes:

  • White Oval Z is just past the central meridian.
  • The Equatorial Zone is orange.
  • The Great Red Spot is on the central meridian.
  • Clouds from the South Equatorial Belt are circulating around the GRS and into the South Tropical Zone to the east.
  • Io and Europa are left and right of the planet respectively.

More Info...
The teal spot that caught my attention in the RGB image is dark.

UTC

It has been a very long time since I've attempted methane band imaging. The good conditions made it seem appropriate to start capturing them again. After this image, a solid deck of clouds came in while working on an RGB set and ended the imaging session.

Notes:

More Info...
There is a subtly dark feature setting on the South Temperate Belt. Is this a new STB structured segment?

UTC

Since I needed to offload the previous RGB, a process which involves freeing a USB port for an external drive, I decided to capture some deep-red/infrared data while I had the USB hub for the focuser and filter wheel disconnected.

Notes:

  • The North Temperate Belt is nothing more than a faint line.
  • The North Equatorial Belt has a new rift past the central meridian.
  • The Equatorial Zone contains an intense festoon approaching the CM.
  • Even though the EZ has traded its typical white color for orange in RGB images, it still looks normal in infrared.
  • The teal spot on the SEBn in the RGB image is very dark in infrared.
  • There is a bright spot past the CM just off the SEBs.
  • Oval BA is approaching the CM with the STB Ghost trailing it.
  • There is a subtly dark feature setting on the South Temperate Belt. Is this a new STB structured segment?
  • The South Polar Red Spot is setting.

More Info...
The South Equatorial Belt has a dark teal spot with a detached tail on its northern edge.

UTC

After a successful set of images with the 90mm Mak and no signs of clouds, we decided to take out the C14 while there was time. Turns out that was a really good decision since this is our best RGB image the apparition so far. However, it did end up being disturbed by a thin layer of clouds.

Notes:

  • The North North Temperate Belt is showing hints of orange within its otherwise brown clouds.
  • The North Temperate Belt is thin. The southern edge is faintly orange while the north is a thin dark line.
  • There is a white oval on the NEBn at the central meridian.
  • The North Equatorial Belt has a new rift past the CM.
  • The Equatorial Zone, except for the southern edge, is still orange. However, there is a subtle orange smudge at the CM on the EZs.
  • The South Equatorial Belt has a teal spot with a detached tail on its northern edge. I don't recall seeing anything with this color on Jupiter before.
  • The SEBs is dark compared to the rest of the belt.
  • There is a bright spot just off the SEBs on the CM.
  • White Oval BA is rising with the STB Ghost trailing it.
  • There is a subtle blue feature to the west of Oval BA. Is this an STB structured segment?
  • The South Polar Red Spot is setting.

More Info...
Oval BA is rising with a stream of dark clouds to its north.

UTC

After a surprisingly successful first set of captures with the 90mm Mak, I decided to step up my game and inserted a 2x barlow into the imaging train. Previous attempts had failed because of poor tripod stability, but this time with the barlow was much more successful.

Notes:

  • The North Temperate Belt is thin. The southern edge is orange while the north is dark.
  • The North Equatorial Belt appears to have a few new rifts.
  • The Equatorial Zone, except for the southern edge, is still orange.
  • The South Equatorial Belt appears to have a dark spot on its northern edge approaching the central meridian.
  • The SEBs is dark compared to the rest of the belt.
  • Oval BA is rising with a stream of dark clouds to its north.
  • The South Polar Red Spot is past the CM.

More Info...
The SEBs is dark compared to the rest of the belt.

UTC

I wasn't expecting to image tonight, but I went outdoors to see the sky clearing to the south. The stars were twinkling and the sky could've clouded over at any time, so we skipped the C14 and I pulled out the 90mm Mak for a quick setup. Sky conditions were very good! I believe this is one of my best photos from this scope!

Notes:

  • The North Temperate Belt is thin. The southern edge is orange while the north is dark.
  • The North Equatorial Belt appears to have a few new rifts.
  • The Equatorial Zone, except for the southern edge, is still orange.
  • The South Equatorial Belt appears to have a dark spot on its northern edge approaching the central meridian.
  • The SEBs is dark compared to the rest of the belt.
  • The South Polar Red Spot is past the CM.

More Info...
The Great Red Spot is highly sheared on the western edge.

UTC

I wasn't expecting to image within the next week. However, I found Jupiter shining through a very thin cloud layer, so I hastily set up the C8 in a race against the clouds that were predicted to arrive at any moment. This was the first light of my new ZWO RGB filters, which I find to be much better than the Orion filters I was previously using with the this telescope.

Notes:

  • Io and its shadow is transiting the North Equatorial Belt.
  • White Oval Z is directly north of the Great Red Spot.
  • The Equatorial Zone is still orange. The southern edge appears to be finally losing its white color.
  • The South Equatorial Belt appears to be split by a white zone. The southern edge of the belt appears more gray than brown.
  • The Great Red Spot is highly sheared on the western edge.
  • Another cloud sheared off the GRS a few days earlier is to the east of the storm.

More Info...
Clouds from the South Equatorial Belt are circulating around the Great Red Spot in a similar fashion to 2018

UTC

This morning was the best one yet for imaging, but I'm still waiting for a knockout morning for imaging.

Notes:

  • White Oval Z is at the central meridian.
  • The Equatorial zone is still colored orange
  • Clouds from the South Equatorial Belt are circulating around the Great Red Spot in a similar fashion to 2018.
  • The SEB following the GRS is pale.

More Info...
There is a bright spot in the South Equatorial Belt, north of Oval BA.

UTC

This imaging session was quite frustrating to get started. I intended to quickly align the telescope with the Moon, but could not find it with the telescope at all! When I finally aligned the scope and aimed at Jupiter, seeing looked very good. However, a group of clouds blocked the view right as I was going to start capturing. When they finally moved away, the seeing had become awful. I also forgot to switch filters on one capture, causing me more frustration with the threat of more clouds looming.

Notes:

  • The Equatorial Zone is orange.
  • There is a bright spot in the South Equatorial Belt, north of Oval BA.
  • Oval BA is near the central meridian.

More Info...
The northern part of the South Equatorial Belt is lighter in color than the southern part.

UTC

It has been many months since we've gotten use with the C14 since my daily schedule keeps me away from it. Unfortunately, seeing wasn't good enough to get anything more than large details.

Notes:

  • The Equatorial Zone is colored orange.
  • The northern part of the South Equatorial Belt is lighter in color than the southern part.
  • A brown barge on the SEB is rising.

More Info...
Oval BA has lost its red color after having it for over a decade.

UTC

Another morning, another imaging session near my university's parking lot, and a surprisingly cold one at that. In fact, the forecasts I checked the evening before were ~10°C warmer than the actual temperature! This time, I had my 3x barlow and the right plugs to avoid using the power strip with my Power Tank.

Notes:

  • There is a complex of small rifts on the North Equatorial Belt, starting at the central meridian and stretching eastward.
  • Oval BA and the STB Ghost are rising.
  • The Equatorial Zone is orange.
  • Oval BA has lost its red color after having it for over a decade.

More Info...
The Equatorial Zone is still orange.

UTC

Seeing improved quite a bit since the last image. I was still manually tracking the planet with the hand controller.

Notes:

  • The Equatorial Zone is still orange.
  • The South Equatorial Belt is split by a white zone.

More Info...
The South Equatorial Belt is split by a white zone.

UTC

At this point of the session, it became apparent that my Celestron Power Tank couldn't handle powering the equipment through a power strip. Since I lost my alignment, I set the speed to 2 and held right on the hand controller to keep pace with Jupiter.

Notes:

  • The Equatorial Zone is still orange.
  • The South Equatorial Belt is split by a white zone.

More Info...
There appears to be little to no wake trailing the GRS.

UTC

This is my second go at imaging from my university. This time, I felt confident enough to bring the C8, and I brought a Celestron Power Tank to power the Advanced VX and keep the laptop charging so it wouldn't prematurely lose power because of cold air. Unfortunately, I forgot to bring the 3x barlow to the field, but I don't think it would've brought in any extra resolution due to lackluster seeing. As with the previous imaging session, transparency was variable from high clouds.

Notes:

  • The Equatorial Zone is still orange.
  • The South Equatorial Belt is split by a white zone.
  • The Great Red Spot is setting.
  • There appears to be little to no wake trailing the GRS.

More Info...
The Great Red Spot is about to set.

UTC

Seeing continues to be good with variable transparency. After this, my laptop battery ran out of power from the cold temperature.

Notes:

  • White Oval Z is past the central meridian.
  • The Equatorial Zone is still orange.
  • The Great Red Spot is about to set.
  • The South Equatorial Belt to the west of the GRS is split by a white zone.

More Info...
The Equatorial Zone is still orange.

UTC

Seeing continued to be good enough for the 90mm Mak, even though high clouds slowly moved through the sky.

Notes:

  • White Oval Z is past the central meridian.
  • The Equatorial Zone is still orange.
  • The South Equatorial Belt to the west of the Great Red Spot is split by a white zone.

More Info...
The South Equatorial Belt to the west of the Great Red Spot is split by a white zone.

UTC

I was getting anxious about having no access to a telescope five nights per week, so I decided to pack the 90mm Mak in the car and use it at my university. I attempted this in February, but my laptop powered down before I could capture anything because of the below-freezing temperature.

Notes:

  • White Oval Z is just past the central meridian.
  • The Equatorial Zone is still orange.
  • The South Equatorial Belt to the west of the Great Red Spot is split by a white zone.

More Info...
There appears to be no wake trailing the Great Red Spot.

UTC

Capturing data was very difficult due to clouds and poor seeing. Unfortunately, I missed a potentially great opportunity to catch Jupiter yesterday by sleeping through my alarm.

Notes:

  • The North Temperate Belt appears to have completely faded.
  • The North Equatorial Belt is very dark.
  • The Equatorial Zone appears to have continued to darken through solar conjunction.
  • The Great Red Spot potentially has no wake trailing it.
