The white light images below are by Dave Tyler showing first AR1109 on 2010 September 25 at 0935 UT and then AR1108 nearing the western limb on the same day at 0937 UTThe third image is a full disk image in H-alpha by Sheri Lynn Karl also on the 25th at 1506 UT
The two images below by Dave Tyler show a flare timed at 1031UT 2010 September 21 and at 1043UT that day a prominence showing loops of magnetism around the flare region.
Well done with this, Tom. I was looking at it this afternoon. There is also a promising group 1026 developing. So tomorrow there should be two significant groups on the disk.
Thanks David. However I must give Dave Tyler credit because I have been having problems getting control of the image with the Toucam and Herscel wedge. He suggested aligning the polarising filter and adding a darker ND filter. Worked a treat.Tom
Yes, Dave Tyler is always very helpful with the technical aspects of high-resolution imaging. He has taught me many things as well. One of those people who is a real credit to the hobby.
Today’s solalr image from the SOHO/ESA site shows new sunspot groups around the north-east lime and also a nice prominence hearth on the H-alpha image.
