Giant filament 16_10_2010. 10.00h UT. I thought the sun had forgotten us here in the NE. Lots of passing cloud meant imaging had to be quick.

A couple of images of AR1121 by Dave Tyler from November 6th and 10th shwoing the group in H-alpha light.

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.
