Type: galaxy (Seyfert 1)
Mag: B=13.1, V=13.7
Size: 1.479′ x 1.174′
Synonyms: H II-194
Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "F, pL, R, mbM."
Burnham calls it a 12.9 mag spiral galaxy in Bootes, 0.5' across, pretty faint, pretty small, round and very suddenly very much brighter in the middle.
(Sulentic and Tifft 1973) notes that this is a 13.5 mag galaxy. Their coded description reads R,HISBCT,DIFPERIPH DKLN NR PERIPH.
This galaxy is listed in the "Third Reference Catalogue of Bright Galaxies" as being a bright Seyfert galaxy. The integrated B magnitude of the stellar system (excluding the nucleus) = 13.30, and the B magnitude of the quasi-stellar nucleus = 14.8-15.8.
Coe, using a 13" f/5.6, notes: "Faint, small, round, very much brighter middle at 100X."
