Notes: A lot of moisture in the air is aggravating light pollution, also observing through well-broken cloud. Dew heaters turned up high. This trio is a very difficult object in these conditions. UGC 717 is at the E end of a crooked line of three 11th magnitude stars. I could see it with direct vision for a fraction of the time, but mostly it was invisible. It appeared as a small oval glow with the major axis SE-NW. The primary companion is UGC 719, mag 14.9 and 0.7×0.7 arcmins. This was visible pretty much the same as UGC717. A second companion is MCG+2-4-2 mag 15.6 and 0.5×0.4 arcmins. I thought I glimpsed this once with averted vision, but was unable to confirm the sighting. |
