I present results of a search of Dwarf Nova Al Com. I studied the light curve of Dwarf Nova system (2009 Outburst of J094002.56+274942.0) by the ROTSE-III robotic telescope. I perform a photometric analysis of the raw images starting with a source extraction package, and then calibrating to known stellar sources. The analysis of the light curve is performed with RPHOT software, and I compute the change of the Dwarf Nova magnitude (brightness) across the duration of the study. At least two superoutbursts are observed over a 4 week period. Additionally, I use a Lomb-Scargle Periodogram to also look for periodic effects. The variation of the light curve provides clues as to the underlying physical mechanisms of the Dwarf Nova system.
