Possible New Variable in Hercules: Var Her 04

A possible new variable has been discovered in Hercules. The nature of this object is not yet known although it now appears to be a catacylsmic variable. It does not appear to be a classical nova, and is quite blue. At this time it appears to be a UGWZ type dwarf novae. UGWZ stars have very infrequent outbursts decades apart.
