Published comments
Burnham's Celestial Handbook
Burnham calls it a 12.7 mag spiral galaxy in Bootes, measuring 0.6' x 0.4', which is pretty faint, small and elongated; lenticular.
Sulentic & Tifft (1973)
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads E,R,BM,BET2*CLOSE.
Modern observations
Steve Coe
Steve Coe, using a 13" f/5.6, notes: "Pretty faint, pretty small, elongated 1.5 X 1 in PA 100 and brighter in the middle at 165X. There are several stars involved at high power."
