The All-Sky Automated Survey for Supernovae (ASAS-SN) Light Curve Server v1.0

Abstract

The All-Sky Automated Survey for Supernovae (ASAS-SN) is working towards\nimaging the entire visible sky every night to a depth of V~17 mag. The present\ndata covers the sky and spans ~2-5~years with ~100-400 epochs of observation.\nThe data should contain some ~1 million variable sources, and the ultimate goal\nis to have a database of these observations publicly accessible. We describe\nhere a first step, a simple but unprecedented web interface\nhttps://asas-sn.osu.edu/ that provides an up to date aperture photometry light\ncurve for any user-selected sky coordinate. Because the light curves are\nproduced in real time, this web tool is relatively slow and can only be used\nfor small samples of objects. However, it also imposes no selection bias on the\npart of the ASAS-SN team, allowing the user to obtain a light curve for any\npoint on the celestial sphere. We present the tool, describe its capabilities,\nlimitations, and known issues, and provide a few illustrative examples.\n
