[vsnet-alert 7673] AD Men outburst - observation needed!



AD Men outburst - observation needed!

   As reported by Rod Stubbings, the dwarf nova AD Men is undergoing a
bright outburst.  This is the first outburst of this star reported to
VSNET.  The present brightness already surpasses the maximum value in
the literature.  Since this field is very crowded, the minimum identification
may not be certain.  We therefore encourage time-resolved photometry
(several hours per night) to examine the presence of any modulations.
The object is also known as a ROSAT X-ray source.

   We would be happy to receive selected CCD images (in FITS format) in
outburst.  The images will be examined for astrometry and quiescent
identification by Yamaoka-san (yamaoka@rc.kyushu-u.ac.jp).

   The nominal position in the catalog is 06:04:28.60 -71:25:15.6 (J2000.0)
