Two ASAS-SN Supernovae in One Day!

So maybe our luck is improving: just two days ago, on August 30th, we announced the discovery of two new supernovae, ASASSN-13co and ASASSN-13cp. Both are rather faint for us, V=16.9 and V=16.6, which is actually a good sign: as we take more data, our data processing is improving, allowing us to see fainter transients. In fact, if you look at our ASAS-SN Transients page, you will see many transients fainter than V=16. Our 9th supernova discovery, ASASSN-13co, is also our first non-Type Ia supernova, again a good sign, being found about 90 Megaparsecs away, quite a bit further than we expected to find core-collapse Type IIP SNe. It is also yet another example where follow-up data from our collaborator J. Brimacombe (Coral Towers Observatory) played an important role in our project.
