[vsnet-alert 10767] Re: Nova Car 2008: astrometry

[Brian Skiff]

     This position seems to be about 1" north of a fairly faint
star (R ~19-20?) visible on the DSS2-red plate-scans.  It is
somewhat brighter on the far-red IV-N plate, but not conspicuous
on 2MASS images.  This star appears to correspond to a Chandra
x-ray source 1BMC 111353.7-611349 (2008A&A...488.1221R) from a
VizieR search.
     Another brighter star that shows up in the various Schmidt
plate-scan catalogues and 2MASS is ~4" south (GSC2.3 S4A8019718 = 
2MASS J11135366-6113533).
     As John Greaves has noted, there are STIS spectra of the
immediate field.
