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.

Historical observations

William Herschel (c.1784)

Synonyms: H II-611

Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "F, S, lE."

Birr Castle/Lord Rosse

An observer using the 72-inch f/8.8 speculum telescope at Birr Castle noted "has a nucleus; elongated np-sf."

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads EL,BM.

Modern observations

Walter Scott Houston

Houston calls this one of "two nice little galaxies that are easily found by starhopping from Alpha Trianguli ... it is a 2.5' by 1.1' elliptical, magnitude 12.1 ... in decent skies a 6-inch should do." Nearby lies NGC 672, and Houston notes: "They are less than one degree apart, so you should be able to squeeze them into a lower-power field."
