NGC 3315. My original thought that this might just be a duplicate
observation of NGC 3314 is unlikely since the discoverer E.P. Austin has an
observation of N3314 on the same night. Also, Austin's description refers
to a "star np neb 1 arcmin." While there is a star 1 arcmin northwest of
NGC 3314, it is actually fainter than another star much nearer the pair, also
on the north side. So, I now support the idea that there is a 30 arcmin error
in Austin's declination (which was not micrometrically measured as some of his
were), and that NGC 3315 is actually ESO 501-G48. RC3, therefore, is most
likely correct. Still, colons go on the identification.
24" (3/28/17): fairly faint, fairly small, slightly elongated, 25" diameter, high surface brightness, gradually increases to the center. A mag 11 star is off the west side [42" from center]. Similar to NGC 3305. Located 13' N of mag 4.9 HD 92036.
18" (3/17/07): faint, small, elongated 3:2 WNW-ESE, 0.3'x0.2'. Located 40" SE of a mag 11 star and 13' N of mag 4.9 HD 92036. HCG 48 lies 9' NE. This member of AGC 1060 (Hydra I) has a disputed identification due to a poor discovery position.
