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 I-111

Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB, cL, iR, gmbM."

NGC/IC Dreyer (1888, 1895, 1908)

This 12th magnitude spiral galaxy is recorded in the NGC as "pretty bright, pretty large, irregularly round, much brighter in the middle."

Published comments

Burnham's Celestial Handbook

Burnham adds: "with faint outer arms extending to 5'."

Arp (1966)

Listed as No. 222 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "amorphous arms."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads IRRR,HISBCT,DIFHALO DIF FIL.

Modern observations

Walter Scott Houston

Houston notes that this 10.2 mag galaxy can be seen in a 5-inch Moonwatch scope, spanning 2.5'. It is also evident in 20x 5-inch binoculars.

Ancient City Astron.Club (1980)

Listed by the Herschel Club, described as "difficult to see, elusive, slight hint of elongation. Situated near a bright field star. 6-inch, 48x."

Steve Coe

Steve Coe, using a 17.5" f/4.5, notes: "Pretty faint, round, pretty bright nucleus, averted vision helps the contrast of this galaxy. There is an attendant galaxy about 20' to the West. I believe it is NGC 7724."

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12M; 5' x 2.5' extent; soft, N-S-oriented blob with brighter center; 14M stellar core; 10M star 9' to W; 40' to SSW is SP GAL N7723."

= Arp 222

POSS: -24 at 11'.8 in pa291.

T&B: four *s w/mags.

15cm - vf, 2'.5 diam. it seems to be a bunch of f *s. BS, Roof.

- whoa! easily the brtst gx so far tonight. a little smlr than -23:

2'x1'.75, vaguely elong ENE-WSW (def not pa30 as per ESGC). classic

vstrong sharp concen to vsm vbr core and vconsp *ar nuc. lies in 10'

circle of six m12.5-13.5 *s. halo seems more extensive on E, and there is

occas disturbance NW of center. BS, 14Oct1990, Anderson Mesa.

25cm - elong, smlr than -23 and a bit brtr. BS, Roof.

30cm - nice at lox. round, well concen smoothly to br non*ar nuc. 2'.8 diam.

hix kills fntr part and changes character: more sharply concen w/sub*ar

nuc. at both hix & lox, I get impression of dk patch just to NE of nuc.

CBL, Roof.

Contemporary observations

Magda Streicher

1998 August

Galaxy, Aquarius

Location: Campsite (23 16 South - 29 26 East).

Telescope: Meade 8" 18mm eyepiece, 36 arcmin f.o.v.

Date: August 1998.

Sky conditions: Not very good.

Description: Fairly bright, round medium size (4arc minutes) with a sudden bright nucleus surrounded with a faint halo. I was particularly struck by the starfield, stars are grouped around the galaxy almost like the digits on the face of a clock.
