NGC/IC Project Restoration Effort

===== NGC 5640. Dreyer has a note in the Scientific Papers that WH's offsets from another comparison star in the sweep, Kasan 2528, are probably to be preferred to those from 4 UMi which were used to reduce the NGC position of the galaxy. Neither position, in fact, is very good. The NGC places the object over a minute of time too far west, while Dreyer's new position places it too far east by about a minute. Both positions are about 3 arcmin too far south. All this assumes that CGCG 353-035 is indeed the object that WH found. In particular, his description "little extended near parallel" (i.e. extended in RA) is much more apt for the brighter component of CGCG 353-034. However, this object is yet another minute of time further to the west from the NGC position. So, I've preferred to stay with the "traditional" identification, though CGCG did not put the number on either galaxy. RNGC, however, got the correct object.

===== NGC 5640 17.5" (7/16/01): extremely faint, very small, round, 20", low even surface brightness. Two mag 15 stars are 1' SE and 2' SSE. An equilateral triangle of mag 10 stars with sides 3' in length is at the east edge of the 220x field. CGCG 353-034 lies 7' W and appeared very faint, small, round, brighter core. It was slightly brighter than NGC 5640 = CGCG 353-035! 17.5" (6/23/01): extremely faint, very small, round, 15". Requires averted vision to glimpse and no details visible. A trio of mag 10-11 stars is at the east edge of the 220x field (22'). This galaxy seems very faint to be picked up by William Herschel while sweeping.
