Per Corwin, the MCG catalog miscataloged PGC 28208, a low-surface brightness galaxy (or pair of galaxies) to the southeast of NGC 3002 as the NGC object; and as a result, many databases (including LEDA and Wikisky) incorrectly list that galaxy as NGC 3002.

Listed in NED as MCG+07-20-052. Because of an error in the MCG listing, identified as NGC 3002 in that catalog, LEDA and Wikisky (but fortunately not in NED, which correctly shows NGC 3002 as a single star). Based on a recessional velocity of 4730 km/sec, PGC 28208 is about 220 million light years away. Given that and its apparent size of 1.1 by 0.45 arcmin, it is about 70 thousand light years across.

The second IC notes "= Javelle #1126, J's Δα should be +18.5 seconds instead of -18.5 seconds" (Δα being the difference in right ascension).

The second IC states "NPD is 55 46.9", the blame for the error being attributed to a misprint.

The second IC lists a corrected RA (per Howe) of 09 43 21.

Nothing exists at the recorded position; perhaps a misrecording of NGC 3051, which see. Several instances are known in which early observers, working without the benefit of photography (which had either not yet been invented or applied to the heavens), recorded a nebula as two separate nebulae, and this is probably one such instance. The cause of the error may be the method used to observe the objects -- sweeping across a strip of declination as the sky rotates westward, then moving westward and slightly north or south, to sweep across another strip of declination. Under such circumstances, an error in recording the time at which an object passes through the field of view can lead to the same object being listed as two separate objects.
