Sun 2020

First light with our Lunt Solar Systems LS60T Hα with double-stack. Sky around the Sun was mostly cloudy with a few clear spots. Very pleased with the result given the circumstances!

Notes:

• An active region on the northwestern limb is rotating into view.

Another round of imaging the Sun. Conditions were a little better than the previous session. I decided to drizzle 150% during stacking to get more resolution out of the data.

Notes:

• Active region 12759 has rotated onto the disk in the 2 days since the previous image.
• Prominences can easily be seen at the 2 o'clock and 7 to 8 o'clock position on the limb.

Another good day for imaging the Sun after two weeks of clouds and rain.

Other than a small prominence on the northwestern limb, the Sun appears featureless aside from its usual texture.

Some minor activity has appeared on the Sun after a rather plain appearance yesterday.

Notes:

• A few bright prominences are on the northwestern limb.
• Two small, faint filaments are near the bright prominences.

Returned to the daytime skies after a week to see the Sun in H-alpha. Seeing and transparency were good.

Notes:

• AR12760 is rising. Its position is near the equator suggests this region is part of cycle 24.

Good seeing and transparency. No active regions visible, but four prominences are extending from the limb.

Clear and stable conditions today. After a couple hydrogen-alpha images with the 60mm Lunt, I swapped in the C8 with a white light filter.

Notes:

• Two undesignated active regions have recently rotated into view.

Clear and stable conditions today. After a couple hydrogen-alpha images with the 60mm Lunt, I swapped in the C8 with a white light filter.

This image focuses on a newly visible active region in the northern hemisphere. A few prominences are also visible on the limb.

Clear and stable conditions today. After a couple hydrogen-alpha images with the 60mm Lunt, I swapped in the C8 with a white light filter.

This image focuses on a newly visible active region in the northern hemisphere. The exposure and gain had to be set at their minimum values for a proper exposure.

Another day of excellent conditions.

Notes:

• The active region in the southern hemisphere appears to have faded compared to the previous day.
• Many prominences are visible all around the limb.

Another day of excellent conditions.

Notes:

• A few nice prominences are visible on the limb.

Good conditions for imaging the Sun on a hot day.

Notes:

• Active Regions 12764 and 12765 are in the northern and southern hemisphere respectively.

Good conditions for imaging the Sun on a hot day.

Notes:

• Active Region 12765 has some plage, filaments, and a sunspot.

Good conditions for imaging the Sun on a hot day.

Notes:

• Active Region 12764 has little activity.

Good seeing on a very hot day.

Notes:

• Active Region 12764 is approaching the northeastern limb.
• AR 12765 is at the central meridian.
• A dark filament is approaching the southeastern limb.

Good seeing on a very hot day.

Notes:

• AR 12765 is at the central meridian.
• A dark filament is approaching the southeastern limb.

A second hot day with stable seeing conditions.

Notes:

• Active Region 12764 is near the northeastern limb.
• AR 12765 is just past the central meridian.
• A dark filament is at the southeastern limb.

A second hot day with stable seeing conditions.

Notes:

• AR 12765 is just past the central meridian.
• A dark filament is at the limb.

Very nice seeing on yet another very hot day!

Notes:

• AR 12765 is just past the central meridian.
• A dark filament is extending beyond the limb.

Very nice seeing on yet another very hot day!

Notes:

• AR 12765 has some filaments and plages.
• A dark filament is extending beyond the limb.

Very hot day of imaging as the humid Texas heat has taken hold this summer. A few filaments are visible across the disk.

Another hot afternoon imaging the Sun. A few prominences are extending from the limb.
