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)

Synonyms:H III-455

Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vF, vL, lbM, easily resolvable, 6' or 7' diameter."

Published comments

Burnham's Celestial Handbook

Burnham calls it a 12th mag spiral galaxy in Cetus, 4' x 4', "very faint, large, a little brighter in the middle. Spiral arms faint."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads SB,BBARW/DIFRG VDIFKN OUTER SSTR.

Sandage and Tammann (1975, Astrophysical Journal, 196, 313-328) includes this galaxy in the NGC 1068 Group. Members include NGC 936, NGC 1055, NGC 1068, NGC 1073, NGC 1084 & NGC 1087.

Supernovae

A supernova erupted in this galaxy in 1962 (13.6b).

Modern observations

Walter Scott Houston

Houston notes that this 11th mag barred spiral is seen as a circular patch about 4' in diameter, forming a diamond-shaped pattern with three 9th mag stars to the southwest. Houston lists this as one of a clump of galaxies within a degree or two of Delta Ceti: the list is in order of increasing difficulty: NGC 1068, 1055, 1073, 1087 & NGC 1090.

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12M; 4' daimeter; face-on spiral; bright center; spiral arms not visible; see photo at HAG-49; about midway and E of a line connecting Gamma and Delta CET; SP GAL N1032 (13M; 1.5'x 0.5' extent) soft slash 1 degree to WSW."

Steve Gottlieb

02 43.7 +01 23 13 (9/3/83): fairly faint, large, even surface brightness, round. An equilateral triangle consisting of three mag 9.5-10.5 stars with sides 5' lies SW.

8 (11/28/81): very faint, fairly large, very diffuse, round. Three mag 10 stars are close SW.

Steve Coe

Steve Coe, using a 13" f/5.6, notes: "Very faint, pretty large, round, not brighter middle."

82-inch at McDonald - Observing Report

[amastro] posting, Sat Nov 25, 2006

82" telescope, McDonald Observatory near Fort Davis, Texas, USA

f/13.7, 35mm Televue Panoptic (5' fov, 812x)

Classic barred spiral, like a dimmer NGC 1365; strong bar, weaker arms that completely encircle the nucleus. In this outer circle there are several H-II knots visible.

Contemporary observations

Tom Bryant

2012 1 15 21:25:14

Observing site: Syria, Va

Telescope: C-11

[2h 43m 42s, 1 23m 0s] A slight brightening of the night sky, seen only when slewing the telescope. 11.0mv seems too bright. B: SBc, 12.0mv. I suspect my corrector plate had iced up making the galaxy appear fainter than it is.
