Seeing continues to be very bad both day and night. Weeks now and counting. Did manage to capture the best seeing of the morning however, some granulation visible!
WHITE LIGHT:
Here is a movie lasting 3 seconds with the refractor and 5x powermate. The atmosphere is VERY unstable!

Lets start with the prime focus shot. I can only get about 1/4 the sun in with one shot, but all the sunspots are seen hereanyway. Besides the new one to the right of center, look on the lower right on the limb - that is the former naked eye sunspot now moving off the limb. It is much smaller now, but may return in two weeks on the other limb!
In Calcium light, the seeing is really bad but you can see the same view as above at this more revealing wavelength.
Here are the prom views of the same limb, not much going on over the big sunspot...
The other limb has some white areas over the disk, but nothing significant
Some 5x Powermate shots in white light. A Powrmate is like a barlow, but projects a more useful light cone out the back which works better with filters. This is shot in green light, with a 520nm filter and a band pass of 10nm. The color yellow here is added later for effect. White suns are boring...
The other sunspot group. Granulation is barely recorded!
Some of the other limbs show proms in Calcium K light. A faint one to the lower right here.
A nice arching prom on the other limb. Remember, Cak proms are very faint, and always look different than what you see in hydrogen alpha light!
