Type: galaxies (interacting), S0p
Mag: B=12, V=18.7
Size: 2.63′ x 2.041′
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."
Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pB, R, gbM, 20 arcseconds."
This 12.8 magnitude spiral galaxy is recorded in the NGC as "pretty bright, pretty small, irregularly round, gradually brighter to the middle."
Listed as No. 223 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.)
(Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads E,R,BM,DIFFILS N.
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."
