William Herschel discovered NGC 4024 = H II-295 on 7 Feb 1785 (sweep 368) and recorded "F, vS, iF, bM." His RA was 30 seconds too large. Howe measured an accurate position in 1899-00 at Denver (repeated in the IC 2 notes) as well as Porter in 1908 at the Cincinnati Observatory.

400/500mm - 18" (3/19/04): moderately bright, slightly elongated, sharply concentrated with a bright 25" core that increases to the center. The fainter outer halo measures ~1.4'x1.1'. An isosceles triangle of mag 10-11.5 stars (sides 2', 2', 4.8') lies 6' W. Located 1 degree NW of the Antennae (NGC 4038/39) in the(NGC 4038 galaxy group.
