We report on the discovery of optical transients by the Catalina Real-time Transient Survey (CRTS)
in data from the Catalina Sky Survey's 1.5m Mount Lemmon Survey (MLS) telescope. The transients
were discovered between 2009-11-11 and 2009-11-24 UT and have the following parameters:
The discoveries were made by comparison to sources measured in MLS coadds reaching magnitude ~23
as well as SDSS, PQ, CSS, CFHT, NOAO and DSS data. MLS091117:035914+133442 appears to be associated with radio source NVSS J035914+133444. All transients were made within minutes of observation and sent as VOEvent alerts. Follow-up is requested.
Additional transients and variable sources from the MLS 1.5m are regularly posted at http://nesssi.cacr.caltech.edu/MLS/Allns.html
Automated event alerts can be obtained from SkyAlert.org.
All CRTS discoveries are made openly available.
