Sun in Hydrogen Alpha

With Coronado PST

Uploaded 8/6/11

 Two large flaring sunspots were visible today, the night after a huge CME impact created aurora over much of the northern US and Candada last night. (We got nothing here in Arizona) Ive included some white light shots to compare to the Halpha images to show how big this grouping was. Ive grouped the images into white light and Hydrogen images separately.
