15 june 2023

I didn't plan to observe last night.  This is marine layer season and frequently it would move in just as darkness falls around 10pm.  But it was still clear as others were going to bed so I decided to give it a try and uncovered the 6-inch.  There were some shreds of fog early but they dissipated, and while transparency was not great, seeing steadily improved.  I had been tired from a lot of house remodeling, but I decided to continue observing well past midnight, finally calling it quits after 1am.  Many objects observed, it was quite a good night.

STF1909 AB: 152; 300x: 44 Boo.  Strongly notched elongation, slight magnitude difference, unfortunately seeing not supporting higher magnification.  This pair is <0.5" now and starting to rapidly widen from periastron, so it will be much easier to split in the coming few years.  SOC grade 2 orbit, 214.7-year period, no Gaia parallax data.

STF2244 AB: 152; 350x: Very pronounced snowman, but not split.  No Gaia data for the secondary.  SOC grade 3 orbit, 474.9-year period, it will hand in the SE for the next couple of decades.
