June 18 2021 Observations

Post by DeepSolar64 »

Session time is from 14:07 to 15:11 UTC. The skies are clear with seeing just above average. The temperature is 73F.


Coronado SolarMax II 90 DS. 32x, 44.5x and 64x ( Ha )
I can see pretty much everything shown on the GONG Cerro Tololo Ha image today. AR12833 in the NE ( Now approaching the CLM ) has a bright plage to the south of the visible spot is easy with a string of filaments running from a large fan ended loop filament off the NE limb to the south of AR12833 branching into two filaments at the active region. The seeing is good enough to show the filaments clearly and they show sharp detail in the scope. I see two more plages in the NW and a ruffled area in the chromosphere in the SW shows several filaments. The SE also shows a filament a bit off the limb.

I can see several prominences around the limb but none are really noteworthy or spectacular. The best one is on the SE limb and is a faint warped M shape.

The discwide mottles are easy and I can see the limb spicule layer today.



Celestron NexStar 102GT w/Altair wedge and 540nm filter. 55x and 110x ( WL )
The large spot of AR12833 shows nice detail today. The umbra shows sharp irregularities at it's edge. The penumbra shows a lot of mottled detail and the radiating detail from the umbra out to the edge. I can see what appears to be five pores near the spot. Strangely the SDO 4K greyscale image shows only three, 4 actually but I didn't notice the close companion to one of them. Anyway the other two may be dark granules. The SDO image suggests that. And I could see the individual granules but it took a close look for their contrast is low and moments of better seeing had to be waited for.

I also see two small spots embedded in a patch of faculae that is near the NW limb.

I see a tiny spot of faculae near the limb in the NE and another similar one near the limb in the SW. I also can barely pick out a larger low contrast patch of faculae in the SW. This one is hard to see.


Coleman, my 8 year old step-grandson viewed the Sun with me through the scopes as I described to him what he saw and why the Sun was colored through the scopes. I also showed him that the Sun was white, not yellow when viewed through the wedge without the filter. That the natural color of our star is indeed, white! Not yellow. I also explained to him to never look through a telescope without these filters because it would burn your eyes out if you did! And to never look through a regular set of binoculars on the Sun and make sure an adult is always with you. The sun can be fun but there is always an element of danger.

He did notice the spot in continuum and the spot, plage and prominences in hydrogen-alpha.

Have a sunny Friday everyone and a good weekend.


James

Hi James

Looks like you had great observations. Say hello to Coleman from my daughter Regina (she's almost three), she really thinks the sun is red after looking at Lunt several times. :)

Ivan,
I really enjoyed observing with Coleman today. I will tell him that Regina said hello.

I hope to observe on Saturday but I noticed tonight upon arriving home from work that the skies were overcast with high thin clouds. This is often a harbinger for an approaching weather system and rain.

Good luck on getting a session in tomorrow.

James

Great to hear they are starting young on their path to a career in science (maybe).

Thanks for your report, James.

I should have done the same. I started out as a science nerd :geek: at a young age. I guess an amateur is all I will ever be, but it is fun!
