Seems as of today you can now view CBETs - that is Circulars from the International Astronomical Union (IAU) without a subscription. These generally detail new discoveries (Comets, Nova, Supernova, Variables etc) by amateurs and professionals and give data on the scientific follow up etc.
As amateurs we will find this is a very valuable resource now made available and the IAU should be congratulated.
Bookmark the site below, then simply click on any of the CBET.
Of course you can click on CBET3007 for details of my latest SN discovery SN2012U
