Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "vF, 30 arcseconds, involves 2 or 3 stars." On a second occassion he called it "The following star (14m) of a vF double star 11m is nebulous. The nebula is excessively faint, but I am sure of its existence. The preceding star is free."

NGC/IC Dreyer (1888, 1895, 1908)

This elliptical galaxy is described in the NGC as "very faint, very small, faint star of a double star involved." It measure 1.2' across and lies at PA 42 .

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a galaxy. Their coded description reads 24-R,STELNUC,DIFHALO.

Contemporary observations

Auke Slotegraaf

1982

In a 15.5-inch telescope, this object shows as a very faint, irregular galaxy, lying due east of a small triangle and 10-11th magnitude stars, and northwest of a bright 90 degree triangle, of which two stars are 9th magnitude. It requires averted vision to see the galaxy clearly. It has an irregular shape as it appears to be elongated southeast to northwest, although this could be due to a small star.
