Discovered 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, has 2 or 3 stars very near it." On a second occassion he called it "F, R, gbM, 25 arcseconds, between two stars." His third observation was recorded as "F, S, lE, bM, 15 arcseconds long, 12 arcseconds broad." The final record reads: "pB, R, pgbM, 25 arcseconds."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads SB,BDDIFARMS,WDBBAR DIF FIL CONNECT ARMS AT ENDSOF BAR.
