Dear CBAers,

This message from vsnet calls attention to a new transient which may 
well be a dwarf nova.  At 12th magnitude, it might be a very nice 
target.  If we can muster observations on both sides of the Atlantic, we 
should be able to define the period content satisfactorily.  Assuming it 
does have periodic variations.

Fire when ready!

    Nishimura-san has detected a bright transient.  There was a 20 mag
star at the position of the improved astrometry.  The object appears
to be a high-amplitude WZ Sge-type dwarf nova.
All sorts of observations are encouraged!
