Corwin's Notes

===== NGC 3465. Though credited only to JH in the NGC, this is probably also H III 967 (see NGC 3500 for more on this). WH found the galaxy on 2 April 1802, but it -- and the other fourteen in sweep 1096 -- has a large, systematic error in its position. Dreyer attempted to sort out the problem in his notes to his 1912 edition of WH's Scientific Papers; most of his conclusions are correct. See NGC 3752 for more, and for the correct solution which Wolfgang Steinicke finally worked out. Also see NGC 3484 for an unsolved mystery possibly related to NGC 3465 -- but probably not. Finally, this plays a peripheral role in the identification of h 917, which see in the "notngc" files.

Steve's Notes

===== NGC 3465 24" (5/25/14): at 375x appeared fairly faint, fairly small, elongated 4:3 ~E-W, 30"x22", contains a very small brighter core and occasional stellar nucleus. A mag 14-14.5 star is just 40" SE. First in the KTG 34 triplet with NGC 3500 9' E and NGC 3523 14.5' ESE. 18" (3/30/05): faint, fairly small, slightly elongated ~NW-SE, ~0.7'x0.5', contains a small, brighter core. A mag 13.5 star is off the SE side and a 29" pair of mag 12 stars lies 3.5' NE. First in a trio with NGC 3500 9' E. 17.5" (4/25/98): extremely faint, fairly small, round. First of three in trio with NGC 3500 9' E and NGC 3523 14.5' ESE. Appears as a low surface brightness spot of 25" diameter (probably viewed core) with little or no concentration. Observation of the group was severely affected by hazy skies.
