NGC 4406
24" (4/28/14): at 260x appeared extremely bright, very large, oval 3:2 NW-SE, 4.5'x3.0'. Sharply concentrated with a very intensely bright core that increases down to the center. The halo increases in size with averted and gradually fades out at the periphery. Brightest galaxy in the central core of the Virgo cluster.
18" (6/12/10): at 175x appears very bright, very large, elongated 4:3 or 5:3 NW-SE, ~4.3'x3.0'. The outer halo gradually brightens then dramatically increases to a very intense 45" core that increases down to a stellar nucleus. The nucleus is fairly well defined as a 20" brighter inner zone. A mag 14.6 star is at the ENE edge of the halo, 2.0' from center. Brighter of a 17' pair with M84 in the core of the Virgo cluster.
17.5" (4/25/87): very bright, fairly large, slightly elongated 4:3 NW-SE, 4'x3', intense core, substellar nucleus, large diffuse halo. One of the two brightest galaxies in the core of the Virgo cluster along with M84 17' W. NGC 4402 lies 10' N.
13" (5/14/83): very bright, larger and more elongated than M84.
