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 II-236

Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, pL, iR, mbM."

Modern observations

Steve Coe

Coe, using a 17.5" f/4.5, notes: "Pretty bright, pretty large, round, bright almost stellar nucleus at 165X. There are two other galaxies in a 30' field of view. That 100X field will also include 96 AQR, a nice white and blue double star."
