Type: galaxy (Seyfert 2), E...
Mag: B=10.8, V=8.67
Size: 6.025′ x 5.37′
NGC 4374. See NGC 4443.
In the Appendix to the 1912 'Scientific Papers of Sir William Herschel' this object is described as "1784, April 17. A bright nebula [The only observation]."
(Sulentic and Tifft 1973) notes that this is a 11.0 mag galaxy. Their coded description reads BE,R,BM.
G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the Virgo I (E) group are NGC 4472, NGC 4649, NGC 4486, NGC 4382 & NGC 4374.
(1961, Astronomical Journal, Volume 66, p555-557) suggests that this galaxy is part of a slightly bent physical chain of galaxies extending over about 1.5 degrees in the Virgo cluster. The eight galaxies forming this chain are NGC 4374, NGC 4406, NGC 4435, NGC 4438, NGC 4458, NGC 4461, NGC 4473 & NGC 4477. Markarian reaches the conclusion, based on a probabilistic argument, that "the chain of galaxies in the Virgo cluster is not a chance grouping but a real physical system."
"nebula, somewhat B at centre, somewhat elongated; spiral?"

A supernova erupted in this galaxy in 1957 (12.2p)
Notes: "Its 9th mag disk is about 2' across, and John Mallas commented that it resembled an unresolved globular cluster in his 4-inch refractor."
Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10M; 4' diameter; 17' W and a little S of M-86; bright, large and round with brighter center; N4388's slash is 17' to SSE; EL GAL N4387 (12.5M; 2' x 1' extent) 7' ESE in center of triangle formed by M-84-86-N4388; NINE galaxies in 1 degree field centered on M-84-86 comprise the "NONET"; most are !good supernova prospects!."
Coe, observing with a 13" f/5.6, notes: "(M84) very bright, large, irregularly round, bright middle. This is the beginning of the Markarian chain, the central section of the Virgo-Coma cluster of galaxies."
Crayon, using an 8" f/6 Newtonian, notes: "(M 84) is an elliptical galaxy. It is 10' 9m and has a suddenly much brighter 3' middle, at 80X."
Instrument:12"Dobsonian Reflector Telescope.
Sky Conditions:The fainter parts of the Milky Way are barely visible.
Transparency of the Sky:Haziness only visible on the horizon.
Seeing:Atmosphere stable with little interference.
Chart Number:No.11(Extract taken out of "Atlas of the Night Sky").
Size:26mm Eyepiece:Field Of View:57'/9=6.3'.
20mm Eyepiece:Field Of View:50'/8=6.2'.
Size in Arc Minutes:6.2'.
Brightness Profile:Low Surface Brightness.
Challenge Rating:A Breathtaking sight to observe in a large telescope under dark skies.
This galaxy is oval and well defined as a large elliptical galaxy.This galaxy has a bright brilliant nucleus.This galaxy's structure has the appearance of a flat rugby ball.This galaxy's appearance in overall is bright.Although this galaxy is bright as most galaxies are concerned.No dark dust lanes are observed.Close to this galaxy I have found a few 12th to 13th magnitude stars within this vicinity.No darker areas have been observed around this galaxy.No areas of uneven brightness are observed around this galaxy.This galaxy has areas of even brightness all over.
Observing site: Pinnacles overlook
