Sol in H⍺ - 13 July 2021

[Hughsie]

Wimbledon has been on the TV so naturally the clouds appear for nearly two weeks.

I managed to capture the the full disc of the Sun this morning then I had to wait for breaks in the clouds to appear. Luckily the afternoon was more fruitful but still suffered from regular interruptions from the clouds. Fortunately I managed to capture some points of interest.

 

Images 1 & 2 - Full disc in colour and inverted. Exposure time 2 ms, Gain = 0. 12% of the best 1,000 frames stacked in AutoStakkert 3

     

 

Images 3 & 4 - AR12842 (Classification Hsx) along with a nice filament and a small straight and curved pillar prom plus an anomalous prom. Exposure 10 ms, Gain = 80. 174 out of 1,000 frames stacked in Autostakert 3. Altair Astro 3x Barlow used. 

      

 

Images 5 & 6  - Straight Pillar Prominence on the South East limb of the disc. Note the same region of the disc in image 2 which was taken at 10 20 UT and highlights its evolution over the next 5 hours. Exposure 10.5 ms, Gain 80. 100 out of 1,000 frames stacked in AutoStakkert 3. Same 3x Barlow used.
