A supernova erupted in this galaxy in 1971 (13.0v)
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads SLEL,S,BNUC,SEV*SUP SEV FDIFWD ARMS.
This galaxy appears on page 20 of "The Hubble Atlas of Galaxies" by Allan Sandage (1961, Washington, DC).

Steve Coe, using a 13" f/5.6, notes: " Pretty faint, pretty small, little elongated and somewhat brighter in the middle at 165X. In moments of good seeing it displays some barred structure. This galaxy that is near the Milky Way and therefore must be loosing some photons to dust clouds between us."
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11M; 6'x 4' extent; see photo at HAG-20."
1997 July 7, Monday, 21:00 - 24:00 Jonkershoek. 11x80's tripod-mounted. Not found; only a star of fainter than 9.5mag seen due North of where the map shows; this star not on the Uranometrias.
Observing site: Pinnacles overlook
[17h 32m 24s, 7° 4m 0s] A slightly oblong smudge, in what appears to be pa 20°. (WikiSky shows it to be closer to 40°. So much for position angle estimates from and alt-azimuth mount!)
