H-Alpha Solar – 21 March2015

Aloha, Todays solar surface showed some interesting features that I tried to capture. There were a lot of long detailed filaments as well as a region to the east that looked like a piece of silk that had been crinkled and then flattened. To the west of this area was a brightening plage, at the moment the brightest region in the observation besides a bright spike on the limb. The prominences to the north were more subtle and dim.
