NGC 1672 = ESO 118-043 = AM 0444-592 = LGG 119-002 = PGC 15941 04 45 42.5 -59 14 50 V = 9.7; Size 6.6x5.5; SB = 13.4; PA = 170d 13.1" (2/19/04 - Costa Rica): fairly bright, fairly large, elongated 3:2 ~E-W, ~3'x2'. Sharply concentrated with a very small, bright core, ~20" diameter, and a large oval halo. Spiral structure was evident as an ill-defined extension or haze off the NE side, though I could not resolve this spiral arm clearly. Situated directly between two mag 9 stars 10' SW and 6.5' ENE. Member of the Dorado group which includes N1515, N1533, N1536, N1543, N1546, N1553, N1566, N1574, N1596, N1617 and IC 2056. Possible additional members include N1559, N1602, N1672, N1688, N1703 and N1705. 18" (7/8/02 - Magellan Observatory, Australia): this striking spiral galaxy appeared fairly bright and large, ~4' diameter, sharply concentrated with a very bright core. Clearly emerging from the east side of the oval core or bar was a spiral arm which curled north and wrapped around two stars to the NW of the core. The extension on the west side was just a very faint, diffuse haze on the SW side without arm structure. A mag 9 star is 6.5' ENE and a mag 6.5 star (HD 30790) is 13' NE. | |||
