Wilhelm Tempel discovered NGC 333 = T I-5 in 1877 with an 11" refractor at the Arcetri Observatory. Tempel's position is 10 sec of RA west and 4' south of PGC 3519. Herbert Howe measured an accurate position in 1898-99 using the 20" refractor at Chamberlin Observatory (repeated in the IC 2 notes). This is a double galaxy (often listed as NGC 333A and 333B) with a very small companion just southwest of the nucleus. Based on RA order, the main galaxy is identified as NGC 333B in NED, RNGC and MCG, and the companion (PGC 3073571) as NGC 333A.

400/500mm - 17.5" (11/6/93): very faint, small, elongated 3:2 ~E-W, very slight central brightening. Almost on a line with two mag 13 stars 3' SE and 5' SE. This is a double system (not resolved).
