Lewis Swift discovered NGC 6248 = Sw. II-44 on 11 Aug 1885 in a group with NGC 6232 and NGC 6236, discovered the previous year. He reported "eeF; pL; R; bet a bright star and 3 stars in a line; v diff." His position is less than 2' west of UGC 10564 and the description is a perfect match. NGC 6248 is an irregular blue barred spiral.

Nevertheless, the RNGC misidentifies UGC 10564 as NGC 6237. In addition, RNGC and CGCG mislabel CGCG 339-036 as NGC 6248. UGC doesn't label 10564 as NGC 6248, but MCG (+12-16-009) has the correct identification. The identifications of these galaxies is covered in my RNGC Correction list #3, Malcolm Thomson's article in the Webb Society Quarterly Journal, July 1989, and Harold Corwin's identification notes for NGC 6237.

400/500mm - 17.5" (7/9/88): very faint, fairly large, very diffuse, elongated 2:1 NNW-SSE, weak concentration.
