[vsnet-campaign 1230] GY Cnc = RX J0909.8+1849 outburst!



GY Cnc = RX J0909.8+1849 outburst!

  The deeply eclipsing SS Cyg-type dwarf nova GY Cnc = RX J0909.8+1849
= HS 0907+1902 is undergoing an outburst.  The dwarf nova has an orbital
period of 4.2 hr.  Observations to follow the eclipses (hopefully full
orbital cycles) are strongly encouraged.  Since the ephemeris is uncertain,
we don't post eclipse predictions at this time.  Please report any hint
of eclipses (either visual observations or with other instruments) as soon
as possible!
