Notes:

These two large Elliptical galaxies (M 84 is to the west <right>) are near the heart of the Virgo cluster of galaxies. The two on-edge galaxies framing this field at the top and bottom are NGC 4402 (at top 4.7'x1.0', 12.6b mag, Cl: Sb sp) and NGC 4388 (at bottom 7.6'x1.4', 11.8b mag, Cl:SA(s)b: sp). Just above NGC 4388 is the smaller NGC 4387 (1.7'x1.0', 13.0b mag, Cl:E). There are numerous other small IC and VCC galaxies in this image.

Contemporary Visual Observation(s) for NGC 4374

NGC 4374 = M84 = U07494 = MCG +02-32-034 = CGCG 070-058 = PGC 40455
12 25 03.8 +12 53 13
V = 9.1;  Size 6.5x5.6;  SB = 13.0;  PA = 135d

17.5": very bright, moderately large, almost round, very bright core, very small 
bright nucleus, halo gradually fades into background sky so there is no sharp 
edge.  Nearly an identical twin of M86 17' ENE but rounder.

13": very bright, very bright core.  Located in the core of the Virgo cluster.

V = 8.9;  Size 8.9x5.8;  SB = 13.2;  PA = 130d

17.5": 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.  N4402 lies 10' N.

13": very bright, larger and more elongated than M84.
