Sun Detail 1-15-2009

Ha Coronado 60mm on 152mm A&M APO, SBIG STL 6303e

We just started a new solar cycle so activity is very low...almost no sun spots in recent months. At least with Ha you can see these tiny prominences and the convection cells on the surface. I like this image as it gives a bit of a 3-D effect to the sun due to limb darkening...even if there isn't much going on.
