Another clear day with good seeing and another spotless day.  A number of filaments in Ha can be seen, but the jewel of today’s sun is the large prominence at the NE limb, which was already visible yesterday.  I had the time today to spend some more time on this than yesterday, and captured data for a 1/2 hour progression animation.  However, I will need some more time to process this, so no animation post today, but an image of the prom.
