This rectangular quartet consists of three NGC galaxies, although NGC 5941 and NGC 5942 (discovered by Lewis Swift) have been misidentified in nearly all modern catalogues. I felt the brightest member visually was NGC 5941 ("B") which appeared faint, fairly small, elongated 4:3 SW-NE, 0.7'x0.5', weak concentration to a brighter core, faint stellar nucleus. NGC 5944 ("A") situated 2.6' SE is very faint, round, 30" diameter, weak concentration with a slightly brighter core. NGC 5942 ("C") is very faint, very small, round, 20" diameter with a stellar nucleus at moments. A mag 14.5 star is off the NW side 45" from center. This is the third brightest in the group. The faintest member MCG +01-40-002 ("D") is 2.0' SE and appears extremely faint, very small, 15" diameter, low even surface brightness. A mag 15 star is 1.1' SE. - Steve Gottlieb
