Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

Historical observations

William Herschel (c.1784)

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads EON,BM,EQDKLN,SLDIF.


A supernova erupted in this galaxy in 1983 (13.0v)

Sandage, A. et al. (1975) Galaxies and the Universe

G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes "Includes the NGC 5566 & NGC 5713 group." The five brightest members of the Virgo III cloud are NGC 5566, NGC 5746, NGC 5713, NGC 5701 & NGC 5584.

Modern observations

Walter Scott Houston

Houston notes that this galaxy lies half a degree west of the 4th mag 109 Virginis. "The star may have to be moved out of the field of view first. The 6' by 1' spindle is readliy discovered in a 10-inch telescope." To the south-west and in the same field lies NGC 5740.

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.7M; 6.5' x 1' extent; bright, large, N-S-oriented slash with brighter center and 15M stellar nucleus; edge-on spiral with dust lane; 14M star embedded or overlying its S end; very, very soft, centerless SP GAL N5740 (12.6M; 2.5' x 1.5' extent) 18' to SSW; 3.5M 109 VIR is the bright star in field 20' due E of N5746."

Steve Coe

Steve Coe, observing with a 13" f/5.6, notes: "bright, large, much brighter middle, much elongated north-south. There is an obvious central bulge at 135X. A dark lane cuts across the galaxy in moments of good seeing."

Observer: Steve Coe

Date/time of observation: 23 May 98

Location of site: Dugas Arizona USA (Lat +34, Elev 4000 ft)

Site classification: Rural

Sky darkness: 7 1-10 Scale (10 best)

Seeing: 7 1-10 Seeing Scale (10 best)

Moon presence: None - moon not in sky

Instrument: 13" F/5.6 Newt. German EQ mount

Magnification: 150X

At 150X in the 13" this galaxy is bright, large, very much elongated 5X1 in PA 165. It has a bright middle and is obviously a very edge-on galaxy. Averted vision makes it grow noticeably longer. There is an obvious central bulge and a 13th mag star in the south arm.

Contemporary observations

Observing site: Pinnacles overlook

Telescope: C-11

[14h 44m 54s, 1 57m 0s] A faint edge on. Looks like a dusty Sc. Nucleus wasn't seen but the middle was a bit brighter than the edged. There is a hint of a sharp dust lane. Burnham classifies it as an Sb.
