On this thread I'll post images from Solar Section members keeping a current view of what the Sun is up to. The first image has been taken in hydrogen-alpha by Paul Rix showing the current active region AR1084 and a whole load of filaments. (South is top on this image.) The second image is a composite by Peter Paice showing AR1084 in white light with hydrogen-alpha and calcium K-line images superimposed.Feel free to post your recent images and post your comments!Lyn SmithSolar Section Director

There is a huge filament on the solar disk just now as this drawing by Erika Rix shows. It's hurricane season in Scotland today so I hope you have better luck observing than me!

Below are two images by Dave Tyler showing southern sunspot AR1084 in Hydrogen-alpha which is now approaching the western limb and also a long filament in the northern hemisphere of the solar disk which has persisted for some days. Both images were taken on 3rd July 2010.

Tom Moran imaged the Sun today 2010 September 14th. He obviously doesn't live in Scotland where we are in the middle of a typhoon!

3 superb images from Dave Tyler. The first is a wide shot of AR1106 on the disk and AR1108 rounding the eastern limb 2010 September 16 at 1418 UT. The next 2 images were taken 2010 September 18 at 0850 and 0927 respectively showing filaments, a flare and sunspot group 1106 and the last image shows AR1108.

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.

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.
For some reason the image didn't post. Â Trying again!
Now for today's H-alpha image.
