Scientific paper

Extreme Ultraviolet Explorer satellite observations were used to identify a new possibly variable source at RA=47.8351, DEC=-22.9106. The EUV light curve shows variability in the 100A bandpass with a hint of periodicity. In the vicinity of this object, there are several possible optical candidates as well as a few unidentified X-ray sources from ROSAT. This analysis leads to the possible discovery of a new variable star, likely to be a cataclysmic variable, a neutron star, or an M star with an active chromsphere. Future observations will be necessary to precisely determine the class of the object and the existence of any periodicity.
