Sun in HAlpha With Lunt LS100THa Uploaded 10/20/13 Daily Report For Sunday, October 20, 2013
 Today the sun had an extraordinary amount of filaments on the disk - proms seen in silhouette against the sun. The sunspots or as we call them in Halpha imaging - Active regions were plentiful and some had some small flaring action. The Proms along the limb were faint, but had some interesting details as we zoomed in.

Next we zoom into the individual regions with the 3x Klee Barlow, resulting in a 6x increase over the above image.

Next, we increase the exposure and lower and gamma to see the prominences on the limb.

Finally, we go off band about 3/4 Angstroms into the "Red wing of Halpha" to see the white micro flares around the sunspots known as "Ellerman bombs"

Thanks for looking!
