Published comments

Burnham's Celestial Handbook

Burnham calls it a 12.9 mag spiral galaxy in Bootes, measuring 0.5' x 0.4', which is pretty faint, pretty small, round and brighter in the middle.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.5 mag galaxy. Their coded description reads R,BM,IRRDIFHALO DKPCHS NP END.
