Corwin's Notes

===== NGC 3119 is perhaps the same galaxy as NGC 3121. There is no doubt about the identification of N3121. This was found by William Lassell in 1848 (see AN 635; my thanks to Courtney Seligman for sending along a copy of the original paper) with one of his smaller telescopes. It was reobserved by Arthur Auwers, who noted the 9th magnitude star 4 arcmin north and 14-15 seconds of time preceding. The position listed by Auwers (1862) is very good. N3119 was found by Albert Marth in 1863 with Lassell's 48-inch reflector. He describes it only as "vF." His position, from one observation, falls about an arcmin southwest of NGC 3121; it is also 2.4 arcmin north of the galaxy that RNGC chose as N3119: CGCG 093-045. This is considerably fainter and smaller than N3121. Wolfgang also favors CGCG 093-045 and reports that it is visible in his 50-cm reflector as a slightly non-stellar patch. So, Marth almost certainly could have seen CGCG 093-045. However, since his position is closer to N3121, and since that galaxy is the brightest in the area, I think it more likely that Marth's observation refers to it. Wolfgang and RNGC could be right, of course -- but then, why didn't Marth mention reobserving the galaxy that his mentor had found 15 years before? Would he even know about it? We don't have answers to these questions.

Steve's Notes

===== NGC 3119 17.5" (1/23/88): extremely faint, very small, round. Located 4' SSW of NGC 3121. Forms the SE vertex of an equilateral triangle with NGC 3121 3.7' NNE and a mag 13.5 star 3.8' NW. The identification of NGC 3119 is uncertain and it may be a duplicate observation of brighter NGC 3121 instead.
