Albert Marth discovered NGC 7554 = m 549 on 3 Aug 1864 and noted "eF, eS, alm stell, near h 2220 [NGC 7556]." His position is just 3 seconds of RA preceding[NGC 7556 and matches PGC 70850.

The RNGC appears to misidentify a faint galaxy 5' southwest of[NGC 7556 as NGC 7554, although there may simply be an error in position for[NGC 7556 as the rectangular coordinates don't match. This error is listed in my RNGC Corrections #5.

400/500mm - 17.5" (7/20/90): very faint, very small, round, low even surface brightness. Forms a close pair with much brighter NGC 7556 47" ESE. Located in a large galaxy group.

600/800mm - 24" (9/29/16): at 375x; fairly faint, small, round, 15" diameter. NGC 7554 is one of the close companions of brighter NGC 7556, which is centered just 48" E.
