The ASAS-SN Sky Patrol (All-Sky Automated Survey for Supernovae) is an automated program to search for supernovae and other astronomical transients, headed by astronomers from Ohio State University (US). It has 20 robotic telescopes in both the northern and southern hemispheres and surveys the entire sky approximately once every day.

Besides detecting supernovae, the project frequently discovers other transient objects such as cataclysmic variable stars, tidal disruption events (TDEs), galactic novae, stellar flares, etc.

Peranso lets you plot ASAS-SN light curves either directly from the Internet or by importing ASAS-SN text files with observations downloaded from the ASAS-SN website.
