Corwin's Notes

===== NGC 2554. There is no problem with the identification of this galaxy, but as Steve Gottlieb recently (April 2014) pointed out, the faint companion (CGCG 119-032) was seen by LdR, but mistaken for a star. The SDSS photometry for this object makes it among the fainter galaxies picked up with the 72-inch (B = 16.53, V = 15.57, and R = 14.94), only half a magnitude brighter than NGC 2603 (which see). I also mention the companion in the "notngc" files, where I essentially repeat this note.

Steve's Notes

===== NGC 2554 24" (2/16/15): at 322x; moderately to fairly bright, moderately large, oval 4:3 NNW-SSE, 1.2'x0.9'. Sharply concentrated with a very bright core that increases to a very small, intense nucleus. A mag 13.5-14 star is barely off the southeast end, 1.2' from center and a comparable star is off the north side, 1.4' from center. CGCG 119-032 forms the west vertex of an equilateral triangle framing the galaxy with the two nearby stars, and lies just off the west edge [1.4' from center]. At 450x it appeared extremely faint (V = 15.5), round, just 6" diameter. Once identified at high power it was also seen at 322x. 17.5" (3/28/92): moderately bright, fairly small, slightly elongated 4:3 N-S, strongly concentrated with an abrupt well-defined very bright core, sharp stellar nucleus, faint halo with ill-defined edge. Two mag 14 stars are 1.2' SSE and 1.4' NNE of center. Located at the north edge of the Cancer I galaxy cluster. CGCG 119-032 is just 1.5' W but was not noticed.
