PCW Memorial Observatory, Zanesville, Ohio USA, Lat 40.01/Long -81.56
Still not quite recovered from the neck surgery, Paul was good enough to open and close the roll off roof of the observatory for me. I was able to carry down the battery supply for the LXD75 for tracking as well as close up (after my session) the southern drop down wall that enables me to view the Sun at the lower altitude. The enclosed area within the observatory certainly helps control the stability of the scope with the winds today at 11.5 mph. The temperature was comfortable at 26F, but with the lack of surface details, I wrapped up the session in just less than an hourâ€™s time.
The haze limited the performance at higher magnification, but with a little patience, I had moments where I could drop down to 7mm (57x) with the zoom eyepiece. Seeing flipped back and forth and the best views seemed to be around 30x magnification.
There were 7 areas of prominences that I was able to record with no significant surface detail. Three of these areas were sketched.
The brightest prominence was about 55 degrees PA and I did a three sketch sequence of it noting the small changes in appearance over 40 minutesâ€™ time span. This was after the original overall sketch of the limb. The basic outline of this prom really didnâ€™t change a great deal. But looking closely within the structure, there was quite a difference in the intricate network.
At 1209ST (1709UT) at the end of the session around 70 degrees PA, a very bright small blob of a prominence appeared and then left just about as quickly. It may have just been that I was able to see it well during a brief moment of steady clear seeing. Still, it was very noteworthy and I was happy to catch it.
