Albert Marth discovered NGC 6999 = m 432, along with NGC 6998, on 19 Oct 1864 and noted "eeF, vS." Although Marth's position (copied correctly into the NGC) is accurate, the RNGC misidentified LEDA 133216 as NGC 6999. This galaxy is located 11' to the north. ESO gives the correct identification. Included in my RNGC Corrections #5.

400/500mm - 17.5" (7/16/93): very faint, very small, round, low even surface brightness. Located 2.2' N of a mag 10.5 star. Brightest member of AGC 3733. Forms a difficult pair with NGC 6998 5.1' WNW. (R)NGC 6999 = 2MASXi J2102037-275216 lies 10' NE.

17.5" (8/27/92): not found from Grandview campground in the White Mountains.
