Steve's Notes

===== NGC 1637 48" (11/2/13): bright, large, slightly elongated SSW-NNE, 3'x2.5'. Contains a large bright core which contains an elongated bright nucleus that appears to be a bar oriented E-W. The appearance is quite irregular due a thick, fairly prominent spiral arm that curves north-south along the eastern side of the halo and bending west as it curves counterclockwise on the north side. A darker gap was evident between the slightly brighter inner edge of this thick arm and the core. A small section of another spiral arm is attached at the SW side of the core. The SW side of the halo is fainter and not as extensive as the NE side, so the galaxy has a lopsided appearance. 13.1" (12/18/82): fairly faint, large, diffuse, elongated 4:3 SW-NE, weak concentration. A mag 13 star is 2.1' NE of center. Located midway between Mu Eridani (V = 4.0) 1 ESE and 51 Eridani (V = 5.2) 1 WNW. 8" (10/4/80): faint, oval, fairly small.
