If you would like to report your observations, VSNet accepts SN observations and compile them for future use. See the How to post your observations sub page for more information.   So, you think that you've found a new Supernova and want to know how to report it? First look at Transient Name Server (or better yet, the search box on this page) to make sure that it has not been reported already.   You can also use the CfA Minor Planet Checker (Updated 5/4/2022) to make sure that what you are looking at is an SN and not an asteroid.   Also look at AAVSO International Variable Star Index or STSCI atlas of Cataclysmic Variables to make sure you are not looking at a variable star.   This is the TNS getting started page which is where to post your discovery.   Updated 2018/01/14 Other good resources:
