Note that two of the above objects were posted on the Central Bureau's TOCP
webpage: 2011ev = PSN J23453124-0756460 and 2011en = PSN J11075056+1859391.
Confirming spectroscopic observations (range 400-950 nm) were taken with the
Palomar 5-m reflector (+ DBSP) on June 26, 27, and 30 UT. The supernovae were
classified based on cross-correlation with a library of supernova spectra
using the "SuperNova IDentification" code (Blondin and Tonry 2007, Ap.J. 666,
1024).
