Observing Notes
Harold Corwin
NGC 2643 = IC 2390. This identity, first suggested by Reinmuth, was taken up by RNGC. The object was found by Marth in 1864. Correcting his position by 18 seconds of time and 11 arcmin leads to IC 2390. The IC object matches Marth's description, and there is no other object in the area (the east edge of the Beehive) that would fit better. NGC 2637 (which see), found by Marth the same night, also suffers from a declination error of 8 arcmin of the same sign, though the RA is only off by 6 seconds.
