Hi,
tonight's unfiltered CCD observation at the Bronberg Observatory
showed the nova suspect still at magnitude 11.4.
nova suspect 20030620.692 11.4CR
MLF
further astrometry will be derived after tonight's CV run.
Considering the visual observation by A Pearce (12.3V), the star seems to
be red or reddened with V-R=0.9, possibly giving support to B Skiff's LMC
G-supergiant interpretation.
Regards,
Berto

It seems likely that this star corresponds to ASAS3
050826-6826.4 which
has V = 14.23+/-0.15. The range is from about 13.95 to
14.6, but how much
of this is noise at the limit of the ASAS survey rather
than variation is
not clear.

Chris Lloyd
