This galaxy pair is located along the border between Virgo and Coma Berenices. The bright Messier galaxy, M90, resides 1.6 degrees due west. My sketch renders the view in the 10-inch equatorial Newtonian at 82X. NGC 4639 is an 11.5 magnitude Sb-type galaxy elongated northeast-to-southwest across a 3'x1' area. About 18' to the southeast, NGC 4654 covers a 3'x1.5' area and is also elongated northeast-to-southwest. A 9th magnitude GSC star sits 3'.5 to the west of NGC 4654 and three 12th magnitude GSC stars extend to the north.
