NGC 4449 = UGC 07592 = MCG +07-26-009 = CGCG 216-005 = LGG 290-017 = PGC 40973 12 28 11.2 +44 05 36 V = 09.6; Size 6.2x4.4; SB = 13.0; PA = 45d 18" (5/8/04): fascinating view of this "Magellanic" system at 323x! The galaxy is very irregular in appearance and surface brightness with a large, bright, elongated core oriented SW-NE. The core appears offset to the south side of the galaxy. Several knots (giant HII regions) are visible outside the core. The brightest is a well-defined obvious patch on the north edge of the galaxy, 1.5' from the center. This object is #15 in Hodge-Kennicutt's 1983 "Atlas of HII regions in 125 galaxies" and it is nearly comparable in surface brightness to the core. Roughly 1' SE is a smaller, faint knot which is collinear with [HK83] 15 and a mag 13.5 star 2.4' east of the core. A third difficult knot can be sometimes glimpsed about 40" SW of [HK83] 15. Finally, attached on the south end of the core there is a larger, bright knot, although initially I though this was just part of the core. 13.1" (4/12/86): very bright, very large, elongated SW-NE, bright core, stellar nucleus. A knot is involved at the north end and the galaxy generally appears brighter to the north of the core. A star is superimposed close E of the core. 8": bright, moderately large, elongated, bright core. | |||
