IC 3177 is almost certainly a defect on the Harvard plate on which Frost found it. The nominal position is in one of the overlap zones on the POSS1, so appears on eight different POSS1 plates -- not one shows a "F streak, ext 2.'5 at 45 deg" as Frost describes it.
I searched for a similar object at reasonable RA and Dec offsets, but found nothing. So, even though I've not seen the original plate, I am quite certain that IC 3177 is a defect on it.
Coincidentally, there is a defect on the DSS (but not on any of the POSS1 prints that I examined) just a few arcmin to the southwest of the nominal position.― IC Notes by Harold Corwin
