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 V-036

Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vF, vL, E nearly in the meridian or a little from np-sf, about 20' long."

Birr Castle/Lord Rosse

Observations with the 72-inch f/8.8 speculum telescope at Birr Castle noted "Oct 16, 1854. elongated north and south; many stars involved."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a cluster+nebulosity in a galaxy. Their coded description reads COND IN 224.

Modern observations


A bright star cloud that is located near the southern tip and close to the western rim of the galaxy NGC 224 (M31). It is easily detected with a good 8-inch on a clear night. It appears as a fuzzy elongated ball, about the same size as M 32 but quite a bit fainter. With a 16-inch under good skies the brightest blue supergiants in this cloud, and elsewhere in the arms begin to resolve visually into tiny 17th magnitude points.

Gramer, Lew (IAAC)

Observer: Lew Gramer; Your skills: Intermediate; Date and UT of Observation: 1997-07-31/08-01, 07:20 UT; Location: Savoy, MA, USA (42N, elev 700m); Site classification: rural; Limiting magnitude: 7.2 (zenith); Seeing: 7 of 10 - pretty good, intermittent haze; Moon up: no; Instrument: 20" f/5 Tectron truss-tube dob Newtonian reflector; (This was an OBSERVING NEIGHBOR'S Tectron 20", with a 2.6"; secondary, better coatings & cleaner optics than mine.); Magnification: 70x, 170x, 210x, 360x; Filters used: None; Object: ngc206, G52; Category: Star cloud, globular cluster (in M31);

Description: The famous star cloud in the Great Andromeda Galaxy was very bright this morning, with a jagged N edge sloping NE-SW; a more irregular S edge, diffuse especially to the SE, and containing a pronounced dark "indentation" near the center of the edge. A globular cluster in M31, known as "G52" in the Luginbuhl & Skiff Observing Handbook, was readily identified with averted vision to the W. An arcing dark lane was VERY striking to the E, NE, and especially SE of the star cloud, where the dark streak was traced through a *degree* of arc- length, curving S and back NE! Roiling clouds of bright and faint "nebulosity" stretched S of n206, with 4-5 small, stark dark lanes bifurcating to the E and W, amid many stellar and more extended brightenings. Worth every minute spent on this object under such clear conditions! (See also the log for two nights later, where I identified several more constituent objects in the great Galaxy!)
