     This star does appear to be relatively blue on the
southern Schmidt survey images (invisible or barely visible on
DSS2 red and far-red plates, but readily visible on the
blue plate).  The GSC-2.2 and SuperCOSMOS coordinates compared:

18 26 30.89 -46 53 03.8   GSC-2.3
18 26 30.93 -46 53 03.5   SuperCOSMOS, epoch 1974.612

Both show blue magnitude 21.4 from independent scans
of the plates.
