NGC 19 (= PGC 759)
Discovered (Sep 20, 1885) by Lewis Swift
A magnitude 13.3 spiral galaxy (type SB(rs)bc?) in Andromeda (RA 00 10 40.9, Dec +32 58 59)
Historical Identification: Per Dreyer, NGC 19 (Swift list II (#4), 1860 RA 00 02 13, NPD 57 55.6) is "most extremely faint, a little extended, 3 very faint stars around". The position precesses to RA 00 09 26.3, Dec +32 51 09, but there is nothing there. However, as noted in the discussion of NGC 6, this is one of several galaxies discovered by Swift on the same night which mostly share an average error of 70 seconds of time too far west and 8' 12" too far south. Applying that correction, Swift's position for his II-4 precesses to RA 00 10 36.8, Dec +32 59 23, less than an arcmin west northwest of the galaxy listed above, and Swift's detailed description of the star field, "in center of 3 very faint stars forming an equilatoral (sic) triangle, two of them double", exactly matches the nearby stars, so the identification is certain.
Note About Confusion With NGC 21: NGC 21 is almost due north of NGC 19, and Swift's incorrect declination for NGC 21 lies about halfway between them. Unfortunately, several catalogs rapidly put together in the 1970's misidentified the southern galaxy as NGC 21. It was only fairly recently that studies of the original observations of NGC objects showed that the southern galaxy was actually NGC 19. So although almost all modern references have corrected the error, a warning about a possible misidentification of NGC 19 as NGC 21 is still appropriate.
Physical Information: Based on a recessional velocity of 4790 km/sec (and H0 = 70 km/sec/Mpc), NGC 19 is about 220 to 225 million light years away, in good agreement with redshift-independent distance estimates of 185 to 235 million light years. Given that and its apparent size of about 1.15 by 0.6 arcmin (from the images below), it is about 75 thousand light years across.
