Two large sunspot groups have just rotated onto the solar disc around the north-eastern limb, AR2993 and AR2994. Visually both groups are impressive and observations are requested throughout their passage. The groups are also active and strong flares have already been detected. M and X class flares are likely.
Observations and images are requested by the Solar Section.Attachments:
Managed to capture them in very gusty conditions here in Edinburgh.

Day 4 and cloud dodging to get anything at all. Very gusty and poor seeing.
The top group shows the most interesting changes, stretching and splitting the umbra.

Best 25% framesDay 6. Very windy but amazingly still clear enough to image the Sun. Having to make sure the filter doesn’t blow off!

Best 25% framesHi Lyn, I am a new member of the BAA and thought I would try and contribute to this thread (my first post on the forum). I took this image on the 21st April at 12:07 UT using a Celestron NexStar 102SLT. I used a 25mm eyepiece and a star diagonal to project the image onto white paper. I have rotated it as best I could to give the correct orientation. There are two versions of the same image. One has the sunspot groups annotated. I hope that this is useful to you.
Day 8. From the forecast for tomorrow I suspect this will be the last day.
