Possible New Nova/Dwarf Nova in Hya
Abstract:
Grzegorz Pojmanski reports on a possible new nova or dwarf nova discovered by the ASAS3V instrument. The previously unobserved object was first detected by ASAS3V at RA = 10h 25m 22s DEC = -15d 42'.4 (assumed J2000) on Jan 26.245 UT at magnitude 12.219 in V.
Justification:
Early CCD observations submitted by Tom Krajci show a hint of modulation with a preliminary period of 0.067 +/- 0.001 days and an increasing rate of decay. Please observe for as long as possible to look for superhumps or other behavior. Use a V filter if possible and go unfiltered if that is the only way for you to achieve 0.01 precision. Nice, long observing runs are needed. Precision is more important than time resolution at this stage so stack if needed. Visual observations are also requested to fill in the gaps of CCD coverage.
