August 24 2021 Observations.

Post by DeepSolar64 »

Session time is from 16:15 to 16:53 UTC. The skies are partly cloudy. The seeing is below average. The temperature is 84F ( 28.8C ).


Coronado SolarMax II 90 DS. 32x and 44.5x ( Ha )
I can see two active regions on the solar disc. AR12859 is easily seen in the NE. I can see three filaments within it's plage. One thin curved one lies above the spot in the SW of the AR like an eyebrow over a cyclopian eye. Another filament divides the plage into sections in the eastern part of the AR. The northern part of the AR has a dark really easy filament that also has a bent shape. The SE has a yet unnumbered AR. I can see fine filaments within it. It's plage is quite bright.

Today is certainly a day for filaments! Outside of the ones mentioned beforehand that are associated with active regions I see two roughly west of AR12859 approaching the LCM. The southern hemisphere is littered with filaments from the SE to the SW. The most noteworthy of these is a double filament with northward pointing " tails " located in the SW not far off of the Central Longitudinal Meridian. I count about a dozen filaments in the southern hemisphere. Most of these are easily seen.

I notice few prominences. The SW limb has some moderately faint wispy ones and I see only a tiny fairly bright spike on the NW limb. There's also a tiny bright mere bump of a prom on the NE limb.

The mottles are easily seen across the disc.



Celestron NexStar 102GT w/Altair wedge and 540nm filter. 55x and 66.5x ( WL )
AR12895 in the NE shows 7 spots/pores to my eye. The SDOHMI continuum 4K image shows a few more. The large spot shows an easy light bridged umbra. The penumbra is easily seen circling the umbra but I cannot see the detail within it that I did yesterday due to the seeing conditions. I cannot effectively use any higher magnification. Faculae follow AR12859 almost to the limb.

I see 5 pores in the AR faculae in the SE. SDOHMIc 4K shows 6.

I can see a patch of faculae just north of the equator in the NW near the limb. It's associated with AR12858. I also see another facula in the SW near the limb.

Despite the seeing I can still see the fine granulation but using higher magnifications to see the individual granules is out of the question.


Carpe Lumen!

Excellent report and the SDO images show well the new AR in the S.E. which is now AR2860 from this afternoon.

At least my previous comment about it being a possible "damp squid" shows that is not the case at last...

Thanks vm
Terry

Terry, sometimes " damp squids " surprisingly mature. Thanks for the compliments.

Interesting news James, it is good to see that the 'bulge' on the limb that Martin discovered is indeed an active region but I would presume it is a decaying region (damp squib rather than the slippery sort), however, if it is starting to develop pores, then maybe it is developing or maybe stuttering.

Nice to read your description, James.
I love when there are a lot of filaments, and as today shows there are still a lot of them.

Thanks for the input and comments everyone. The " damp squib " is now a full fledged active region. AR12860. I will be posting today's observations shortly.

Eric, good luck on sunny skies.
