Ha Full Disk 19th January

Activity seems to be increasing again on our star over the past couple of days, with several new active regions appearing over the limb. Looking at the prominences and the STEREO spacecraft data there would appear to be more to come too. The higher sun worked in my favour today, and I was able to use the DS40 to produce a 6 pane mosaic taken at f20 with the DMK31 camera. I really like all the intricate filaproms that are visible on todays disk!
