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

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 5865 = NGC 5868. Here, RC3 followed Dreyer (1912) who writes that NGC 5865 should be deleted since NGC 5868 is = H II 684 (WH's position is enough off that JH thought N5868 a "nova"). Dreyer is right -- there are only two bright galaxies in the area, not three (or four as Tempel claims; see NGC 5871 for more on this).

So, I will let RC3 stand as is. However, since both NGC numbers clearly refer to the same object, there can be no confusion if N5865 is adopted.

Historical observations

William Herschel

Discovered on February 24, 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, S, iE, lbM." The Notes to the Second Catalogue read: "In Sweep 727, April 11, 1787, H. saw two nebulae, both described as pB, S, iE, . . . noting one was = II.545. This agrees with d'Arrest and Bigourdan, but the north one is not pB but eF. Perhaps the description of the south one was by a mistake given twice. NGC 5865 = NGC 5868. Only one seen at Birr Castle and by h."

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.5 mag galaxy. Their coded description reads SO),R,SMBM.
