Hi Lyn, this is embarrassing. I forgot to subtract an hour from my timing of my solar image I took on the 21st April. So this should read 11:07 UT not 12:07 UT. Sorry about this.
A huge thank you to all that have contributed images and observations during the transit of AR2993 and AR2994. An excellent photographic record of these groups now exists in the Solar Section archive. Great response from BAA members!
