Large prominence on southeastern limb of the H alpha sun

Recommended Posts

Posted (edited)

Dear all,

today morning I had a look at the GONG network images on the internet and set up my telescope to have a look at that awesome large prominence on the southeastern limb of our home star. First I concentrated on a sketch of just that wonderful prominence. After that, I created - as usual - a sketch of the full solar disc. I noticed that the prominence already had changed during my sketching time.

Nice sketch, thanks for that, hadn't got around to looking this morning, clouds gradually clearing so will get setup shortly.

Hi Achem,

Sorry I've been a bit slow in checking on here. I love the close-up detail sketch of the flare coming away from the side. Brilliantly done.

Very nice flame Acr  (:

What kind of paper are you using? I want to try a new kind of paper myself this one looks rough, I like that. Can it be used with graphite pencils do you think ?

      I heard the sun wasn't very active at the moment. Is it still active when you look through H-Alpha? (I don't really understand the difference!)

      Dear all,
      now the summer heat seems to be gone. It's still sunny but not that hot anymore. Perfect weather for sketching for the H alpha sun:

      Telescope: Lunt LS50THaB600PT
      Eyepiece: Celestron X-Cel 10mm
      Date & Time: August 30th, 2019 / 1230-1300 CEST
      Location: home terrace, Dusseldorf region, Germany
      Technique: reddish Koh-i-Noor Toison d'Or pastels and pastel pens on yellowish Canson Mi-Teintes pastel paper
      Clear and sunny skies!

      Dear all,
      today once again, I did a charcoal sketch of our star bringing us 33°C before lunch time. The solar "north pole" is approximately at the prominence at the top of the sketch. The sketch is right-left flipped. Beside the orientation of the north pole, I figured out on the internet that the bright spot in the left area of the sketch is AR12745. The disc and parts of the prominences is done with natural charcoal. The filament and the dark areas of the prominences are done with the charcoal pen.

      Dear all,
      as usual, I couldn't resist to create yet another charcoal sketch of the H alpha sun. It is relaxing for me to observe the proms and filaments and to try to catch them "as they are" on the paper. At first glance, the sun looks pretty similar - just at second glance and comparison with my other sketches, I have seen that it looks similar but always a bit different. The disc and the prominences are done with natural charcoal, just for the filaments, I needed a Koh-i-Noor artificial charcoal pen since it's darker.
