The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long baseline
(${sim}4$ yrs) light curves for sources brighter than V$lesssim17$ mag across
the whole sky. As part of our effort to characterize the variability of all the
stellar sources visible in ASAS-SN, we have produced ${sim}30.1$ million
V-band light curves for sources in the southern hemisphere using the APASS DR9
catalog as our input source list. We have systematically searched these sources
for variability using a pipeline based on random forest classifiers. We have
identified ${sim} 220,000$ variables, including ${sim} 88,300$ new
discoveries. In particular, we have discovered ${sim}48,000$ red pulsating
variables, ${sim}23,000$ eclipsing binaries, ${sim}2,200$ $delta$-Scuti
variables and ${sim}10,200$ rotational variables. The light curves and
characteristics of the variables are all available through the ASAS-SN variable
stars database (https://asas-sn.osu.edu/variables). The pre-computed ASAS-SN
V-band light curves for all the ${sim}30.1$ million sources are available
through the ASAS-SN photometry database (https://asas-sn.osu.edu/photometry).
This effort will be extended to provide ASAS-SN light curves for sources in the
northern hemisphere and for V$lesssim17$ mag sources across the whole sky that
are not included in APASS DR9.
