Pastel sketch of the H alpha sun with awesome prominence, July 31st

Recommended Posts

Posted (edited)

Dear all,

after coming home from work this afternoon, I decided to do a solar sketch in my garden at pretty hot 35°C. Now cooling down in my 23°C living room with the blinds down, I'd like to share a striking large prominence at the limb with you. I have never seen such a large one before:

Beautiful sketch and amazing catch Achim! A little bit scary- that must be many earth diameters long? How long would a prominence like that last?

It seemed to be over x16 the diameter of the Earth in height.

Flares like this only survive a few hours.

I'm just coming in from my terrace: Indeed the large prom is gone.  So I'm even happier that I caught it yesterday. :)

Clear and sunny skies!
