This X-ray selected dwarf nova in Andromeda (RX J2319.6+3647 = NSVS
9022680 = USNO-B1.0 1267-0564384) has brightened in last 24 hours, as
shown by observations with the Bradford Robotic Telescope:

  YYYYMMDD(UT)   mag  observer
  20101226.006   189  BRT (R229996)
  20101226.962   150  BRT (R238785) outburst!!!

Previous observed outburst:

  20091105.022   145  BRT (R165989), see ATel #2282

Time-resolved photometry is strongly encouraged!  The orbital period
is still unknown. The star has not reached its maximum brightness yet,
so we seem to be lucky to catch this outburst at its early stage.
