| Summary:
Utilizing high-cadence and continuous g- and r-band data over three nights
acquired from the 3.6-meter Canada France Hawaii Telescope (CFHT) aimed to find
short-duration microlensing events, we conduct a systematic search for
variables, transients, and asteroids across a $sim1^circ$ field of view of
the Andromeda Galaxy (M 31). We present a catalog of 5859 variable stars,
yielding the most extensive compilation of short-period variable sources of M
31. We also detected 19 flares, predominantly associated with foreground M
dwarfs in the Milky Way. In addition, we discovered 17 previously unknown
asteroid candidates, and we subsequently reported them to the Minor Planet
Center. Lastly, we report a microlensing event candidate C-ML-1 and present a
preliminary analysis.
