Mars 2018

UTC

Seeing remained decent. After this photo, clouds from the south took over the sky and ended the night of imaging.

Notes:

  • There's a faint cloud above the dust storm in much of the southern hemisphere east of the central meridian. At this point, it has become fainter than earlier in the night.
  • Mare Cimmerium is setting.
  • Most of the south polar cap is covered by dust. The cap also appears to have a hole.
  • Hellas Basin is under a bright cloud of dust.

Seeing continued to be decent. Saharan dust limited transparency, but not as much as the previous night.

Notes:

  • There's a faint cloud above the dust storm in much of the southern hemisphere east of the central meridian.
  • Mare Tyrrhenum is hidden under a completely opaque part of the dust storm.
  • Mare Cimmerium is relatively visible compared to other dark features.
  • The brightness of the south polar cap is muted by the dust storm. The cap also appears to have a hole.
  • Hellas Basin is under a bright cloud of dust.

I decided to capture an IR photo part-way through our time with Mars. Seeing did not improve, but the IR filter cut through some of it.

Notes:

  • Syrtis Major is rising.
  • Mare Tyrrhenum is visible despite being hidden in RGB.
  • Mare Cimmerium is under a thinner veil of dust, making it more visible.
  • The south polar cap appears to have a hole.

Seeing improved again, but clouds returned and ended the session after this photo.

Notes:

  • Syrtis Major is approaching the central meridian.
  • Sinus Meridiani is rising.
  • Dust clouds appear to be escaping from Hellas Basin.

Seeing improved slightly and transparency remained volatile.

Seeing was not bad, but not as good as July 14th, and transparency was extremely variable due to clouds coming through. While processing the Mars images from this night, our hard drive started slowing down and eventually started giving I/O errors, usually a sign that a drive has failed. Fortunately, restarting my computer fixed all the problems but I decided to back up the remaining 1 terabyte of unprocessed data to another drive to be safe.

Notes:

  • Syrtis Major is rising.
  • Dust clouds appear to be escaping from Hellas Basin.
  • The south polar cap is mostly obscured by dust.

Before clouds took over the sky, I felt the need to capture an IR photo. Seeing remained great, but clouds decreased transparency.

Notes:

  • Part of Sinus Meridiani is completely obscured by airborne dust.
  • Syrtis Major is past the CM.
  • The opaque (in visible light) cloud over Hellas Basin and the surrounding area is more transparent in IR.

The last RGB photo of Mars for the night. Seeing continued to be great.

Notes:

  • The NPH is peeking over the limb.
  • Part of Sinus Meridiani is completely obscured by airborne dust.
  • Syrtis Major is past the CM.
  • An especially thick cloud of dust is obscuring Hellas Basin and the surrounding area.
  • The SPC is partly obscured by airborne dust.

Clouds ended the imaging session after this photo.

Notes:

  • The north polar hood is peeking over the northern limb, presumably above the dust.
  • The global dust storm has left a very opaque view of most of the surface.
  • Hellas Basin appears to be covered by a completely opaque cloud of dust, which also appears to be extending east out of the basin.
  • The south polar cap is covered in dust on the eastern side, but mostly clear on the western side.

Seeing became good after we moved on from Saturn to Mars. However, clouds were passing through the area, leaving me to make quick captures when an opening passed in front of Mars. I believe a good color balance for the ASI224MC has been found after two years of working on it. It leaves the surface color a little paler than I like, but features that are white are now appear white in photos taken with this camera.

  • The north polar hood is peeking over the northern limb, presumably above the dust.
  • The global dust storm has left a very opaque view of most of the surface.

My first image of Mars this apparition. This is the first time I'm using an Orion Luminance filter for UV/IR cut. I was hoping to use it to improve color balance using the south polar cap as a reference for white, but the dust storm obscured it to the point of being useless.

Notes:

  • Dust is covering much of the visible northern hemisphere of the planet, but the summit of Elysium Mons appears as a dot near the limb.
  • Mare Cimmerium and the surrounding regions are visible, most of it past the CM.
