Corwin's Notes

===== NGC 3284 = NGC 3286 is the brighter of two galaxies found by WH in April of 1793 (the fainter is NGC 3288). The number N3284 applies to H III 912 seen on the 8th of April, while N3286 belongs to III 917, found the next night along with N3288 = III 918. The GC/NGC position of N3284 is 10 seconds too small (presumeably a reduction or transcription error) compared to my re-reduction of WH's position, so Dreyer did not comment on the possible identity until he prepared WH's papers for their 1912 publication. There he also notes that Bigourdan did not find N3284. A few other objects found the same night by WH show no systematic offset in their re-reduced positions, so the declination offset implied by the identity with N3286 is unique to III 912. The explanation adopted by RNGC (N3284 is a star) is considerably less likely.
