I've never seen a prominence quite like this before.
Made me late to work today.

webcam capture through a 5" Zeiss refractor with 90mm H-Alpha filter.

Hello,



I love these H-Alpha sun pictures. They have such a "Ansel Adams" look to them.

Hi Robert -

Robert Heffner said:

Have you made any animations of these prominences?
(not sure how fast or slow they progress)

They move very fast. Images taken a few minutes apart at high magnifications will often not line up. I've done some animations in the past - this one covering about 20 minutes is looking at an active region head on:

The seeing was especially poor yesterday - I captured a quick stream and called it a day.

Thanks for your comments!
Alan

Love your titles Alan grin

But the image is even better 8O

Lovely prominence with the detached matter and still some "strings attached" to the main body.

Hi Alan,

What an amazing image, the higher prominence looks almost like a cloud.

Thanks,
