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-230

Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "eF, eS, 240 left some doubt."

Published comments

Arp (1966)

Listed as No. 298 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "absorption, knots. Note apparent re-entrant spiral arm on southern galaxy."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.5 mag galaxy. Their coded description reads SLEL,HISB,VFDIFPCHRG COM 1'NF.

de Vaucouleurs, G. et al. (1991) Third Ref. Cat. of Bright Galaxies (RC3)

This galaxy is listed in the "Third Reference Catalogue of Bright Galaxies" as being a bright Seyfert galaxy. The integrated B magnitude of the stellar system (excluding the nucleus) = 12.80, and the B magnitude of the quasi-stellar nucleus = 14.7-15.5.

Steve Coe, using a 13.1" f/5.6, notes: "NGC 7469 Very faint, small, somewhat elongated and not brighter in the middle. It was just seen at 100X, higher powers did not seem to make this galaxy more noticeable."

A comparison star chart for this galaxy with a variable nucleus appeared in Sky&Telescope, May 1978, p372. A 24' wide chart with 9 comparison stars is given, listing V, B-V and U-B values.
