NGC/IC Project Restoration Effort

===== NGC 4501 = M 88. See NGC 4579.

===== NGC 4501 48" (4/5/13): a thin spiral arm was clearly visible extending along the entire western flank of the halo and stretching 4.5' from NW to SE. This arm separates more cleanly from the central region as it extends south, reaching a wide double star (13.7/14.3 that is superimposed on the southeast end. A fainter, very thin, straight arm was also visible along the east side of the galaxy, extending towards the northwest. This arm hugs pretty close to the east side of the core, and separates a bit on the north side. 17.5" (4/25/87): very bright, very large, elongated 5:2 NW-SE, brighter core, intense very small or stellar nucleus (Seyfert 2 galaxy). A faint double star is embedded at the SE end (mag 13.5/14.5 at 20"). A brighter double star mag 11/12 at 30" is 5' S of center. Located at the NE end of "Markarian's chain" in the core of Virgo cluster.
