Abstract

The All-Sky Automated Survey for Supernovae (ASAS-SN) is the first optical survey to routinely monitor the whole sky with a cadence of ∼2–3 d down to V 17 mag. ASAS-SN has monitored the whole sky since 2014, collecting ∼100–500 epochs of observations per field. The V-band light curves for candidate variables identified during the search for supernovae are
classified using a random forest classifier and visually verified.We present a catalogue of 66 179
bright, new variable stars discovered during our search for supernovae, including 27 479 periodic variables and 38 700 irregular variables. V-band light curves for the ASAS-SN variables
are available through the ASAS-SN variable stars data base (https://asas-sn.osu.edu/variables).
The data base will begin to include the light curves of known variable stars in the near future
along with the results for a systematic, all-sky variability survey.
