Sun in Hydrogen Alpha / CaK With Coronado 40 / Lunt 60mm CaK Uploaded 9/11/11
 Saturday the sun was alive with action, several small flares in the hydrogen alpha wavelengths. Here are some full disk shots, and comparisons in both wavelengths. AR1289 is very active, and flares nearly every day creating aurora in the northern polar regions. It will be exciting to watch the development of this region!
