The RASS-PSC object is nearer to GSC 5495 0713 [GSC mag 14.6], which
coincides with galaxy MIG0853595 of integrated B magnitude 16.9, and is
noted as an "excellent fit".

Many faint galaxies occur in this area, with their density increasing
pretty soon towards the south.  There is no indication of any galaxy
cluster, but I have little information on Virgo Cluster sub-groups
["galaxy clouds"].

GSC 5495 0944 has no galaxy listed at that position, and I can find no
evidence of QSO, BLLAC, AGN or radio sources at that position either.
