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.
