Further to ATel#3081, we report the CRTS discovery of 140 optical transients in data taken by Mount Lemmon Survey (MLS) 1.5m telescope between Dec 1st and 26th. All MLS data were processed for transients in real-time by CRTS and discoveries were openly announced at http://www.skyalert.org/. Details of these and other optical transients discovered in MLS data can be found at http://nesssi.cacr.caltech.edu/MLS/Allns.html The discovery details of 13 new supernova candidates are as follows:
