Observing Notes

Harold Corwin

IC 817 = IC 3764. Schwassmann's position is accurate, and -- surprisingly -- so is Swift's. This hasn't prevented confusion in the area, though, as IC 816 is close preceding (and a bit south; Swift's notes have the relative positions flipped north to south -- IC 817 is "nf of 2", not "sf"). Ames has incorrectly equated IC 816 with IC 3764.

I wonder if Swift has mixed up his notes on IC 816 and IC 817. IC 817 is the fainter galaxy, and has the wide double star only 4 arcmin northwest. Yet Swift calls IC 816 the fainter of the pair and mentions the star in its description. And there is the nf/sf switch, too. So, I wonder...
