Error on chart? PGC 3517878 (Answer: Update The IAPs)
Is this an error in SkySafari Pro? Searching Andromeda for galaxies I came across one labelled as PGC 3517878 which immediately raised some suspicion as the number is too long and detailed as mag 8 and 6x6 arc min which surely would be a notable Object. Looked at the DSS image and nothing there, searched Simbad and nothing shows either
