Thursday's Sun in H-Alpha, 2/6/14
Posted by DaveMitsky on Friday, February 07, 2014 3:38 PM

Yesterday afternoon I was able to see the large sunspot group AR(1)1967 without magnification using a pair of black polymer solar eclipse shades.  I then set up my 40mm f/10 Coronado PST and observed the sun in the light of H-alpha. Other than the active region, which was approaching the leading limb, and a couple of small prominences and filaments there wasn't much to be seen.

Chance favors the prepared mind.

A man is a small thing, and the night is very large and full of wonders.
