[vsnet-alert 5740] Nova Sgr 2001 progenitor

Nova Sgr 2001 progenitor

   If the 16-17th mag, red star close to the outbursting object is confirmed
as the progenitor of the nova, the nova may be a recurrent nova, having a
bright quiescent counterpart and a high ejection velocity.  In such a case,
the evolution of the nova may be extremely rapid.  Dense follow-up
observations (including nightly spectroscopy, multicolor photometry etc.)
are very crucial.  A search for past outburst may be meaningful.
