November 17 2020 Observations

Post by DeepSolar64 » Tue Nov 17, 2020 5:32 pm

Session time is 11:00am to 11:58am EST local time ( US ). Skies are clear with windy conditions. Seeing well below average. Temp is 52F.

Coronado SolarMax II 60 DS. 16x and 21.5x ( Ha )
Today poor seeing caused me to really have to work at it to see details. Everything was really soft. The only two things I could see fairly easily on the disc is the plage to AR12782 now entering the SW quadrant and a broken open-looped filament in the NE. Closer and more deliberant observations revealed more details. A new disturbance in the SE and two filaments SE of AR12782. I was also able with difficulty to pick up a filament NW of the new disturbance. Also another NW of AR12782 associated with a weak disturbance located there. I could not see the disturbance today. I can also see a small filament in the NW.

Surprisingly the prominences are not that hard to see, even in doublestack. Three decent ones in the NE with the northernmost one near the half-broken open loop filament. I can actually see two tiny proms above it! The fourth is a hedgerow below the emerging disturbance. GONG Cerro Tololo shows a couple of other small fainter ones elsewhere around the disc but I cannot see them.

The mottles are really soft today but visible covering the solar disc.


Orion 70mm Solar Telescope. 27.5x and 41.5x ( WL )
I can see a single spot and the faculae which corresponds to the disturbance seen in the SE in Ha. I can only barely see the dark spot in the middle that marks the umbra. SDO shows a light-bridged umbra. Seeing will not permit higher magnifications which would show it. I see no other details on the white-light disc. The granulation is rendered invisible by the seeing.

Carpe Diem!

James

Thanks James for the latest.

Awaiting a clear-spell here for some R2 imagery.

Terry. You just need some D2 to go with it. Then you would have an R2D2 system! 🤖

Thanks James, just cloud and drizzle here today, one of my colleagues described it as 'fieldwork weather'.

I hope I get some clear skies over the weekend.

Good to see your review James!

Overcast with cold north wind and snow here...maybe clear tomorrow though.

The sort of weather on a geological field trip in the UK - wet, rainy, damp, windy. Basically weather only the determined go out in :D

Sounds a bit of a struggle today James but at least you got out observing :hamster: I'm glad you are feeling better now though, sorry to hear you were sick :(

Thank you Alexandra. I am just now really getting over it. I am glad it wasn't COVID-19!
