Quite a few prominences visible today, as well as a few sunspot groups. The white-light view is fairly good, using a Baader visual filter. I'm amazed at how, apparently, the water vapor in the air can make some details in H-a less visible. Today is much better than other recent days. The view through "sucker holes" on mostly overcast days is never as good as a day with lower humidity, from my experience. If I had the time, I'd actually research the absorbtion factor of water vapor on the H-a wavelength. Maybe it's something else entirely? Call-out for nerds with lots of free time and the need to know! After a long, hard day at work in a 92-degree shop, I am headed for a bowl of my wife's home-made chicken-noodle soup and a cold beer, and have suddenly lost interest in physics- for now. ;-)
