Abstract

The All-Sky Automated Survey for Supernovae (ASAS-SN) is the first optical survey to monitor the entire sky, currently with a cadence of $\lesssim 24$ hours down to $g \lesssim 18.5$ mag. ASAS-SN has routinely operated since 2013, collecting $\sim$ 2,000 to over 7,500 epochs of $V$ and $g-$band observations per field to date. This work illustrates the first analysis of ASAS-SN's newer, deeper, higher cadence $g-$band data. From an input source list of ${\sim}55$ million isolated sources with $g<br />18 pages, 21 figures, 1 table. Submitted to MNRAS. The g-band catalog of variables and their light curves are available here: https://drive.google.com/drive/folders/1gxcIokRsw1eyPmbPZ0-C8blfRGItSOAu
