V344 Ori bright outburst: call for time-series observations

   The dwarf nova V344 Ori is reported to be undergoing a relatively rare,
bright outburst.  The last outburst was reported in 1999 November (mv=14.0),
but the present outburst is the brightest in recent years.  The present
outburst outshines the GCVS maximum (14.2p).  The quiescent counterpart
has been suggested to be a 18-th mag USNO star, which is not markedly blue
This may suggest that the true quiescence of V344 Ori may be fainter.
(see, however, the spectroscopic observation given in Munari et al. A&AS 122,
495, which shows strong balmer emission lines).

   Accurate astrometry in outburst is also very desired.  The object is
clasified as UGZ: in the GCVS, which very disagrees the present outburst
behavior.  Thus may have been a similar case of AQ Eri and TT Boo, which
had been classified as UGZ: until the detection of superhumps.
