[vsnet-alert 92] brightening of NSV06481

  K. Takamizawa (Nagano, Japan) reports his photographic discovery of
a brightening of NSV 06481.  The original observations follow:

object         YYMMDD(UT)   mag  code
NSV06481       940506.595  141P  K.Takamizawa
NSV06481       950328.660  124P  K.Takamizawa

Instruments: 10-cm refr. (fl=400mm) photographic. T-Max 400

  M. Iida (Nagano, Japan) further reports that NSV 06481 is cataloged
in NSV as a suspected variable star with a range of 14.5 - [15.5 p, type
unknown.  The object is not registered in IRAS PSC.  Hence NSV 06481 seems
less likely to be identified as a red variable.

  M. Iida further provides his survey of photographic atlases:

  Vehrenberg:  fainter than 15.4
  Lick:        14.5:
  GSC:         14.9

  An examination of a photograph by K. Takamizawa confirms an identification
of NSV 06481 with a GSC star (V=14.9) at the corresponding position.

  Although the materials have not been conclusive, M. Iida suspects this
object to be a some sort of eruptive or cataclysmic variable.  Follow-up
observations are urgently needed.  Spectroscopic observations and multicolor
photometry would be most helpful.
