Variable Stars - 1RXS J105010.3-140431
Type WZ Sagittae WZ Sagittae type subclass of UGSU dwarf novae in which the interval between super-outbursts is unusually long (that is due to a very low mass-transfer rate), measured in decades, while normal outbursts are few and far between. They show re-brightenings. Orbital periods range from 0.05 to 0.08 d. AAVSO Alert 350: April 30, 2013 The HST team will be making a final decision on observing 1RXS J105010.3-140431 based on the observations of May 8/9, and observations from the following night will also be essential. Close monitoring of 1RXS J105010.3-140431 through May 11 is requested to be sure it is below the threshold brightness and to have a good magnitude value for correlation with the HST observations. 1RXS J105010.3-140431 is V=17 at minimum; its magnitude at maximum is unknown.
