A spectrum of CSS110116:114913+382427 was also taken with the APO 3.5m +DIS and shows a  
featureless blue continuum with a faint, unresolved emission line at 6988.5 Angstroms.  
The nature of this event is remains unknown.  
 
In addition to the SNe noted above, a SN the candidate, SNhunt31, discovered by Howerton et al.  
(2011, CBET#2637) on 2011-01-10 was found to be the outburst of an LBV in NGC 3437. Two additional  
sub-luminous events (SNhunt23 and SNhunt32) with Mv ~ -15 have also been discovered in NGC 3016.  
Follow-up of these events is encouraged. Information about SNhunt discoveries can be found at http://nesssi.cacr.caltech.edu/catalina/current.html
