During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN or "Assassin"), using data from the quadruple 14-cm "Brutus" telescope in Haleakala, Hawaii, we discovered a new transient source, likely a CV.

ASASSN-14lr was discovered in images obtained 2014 UT December 07.41 at V=15.5 mag. We also detect the object in images obtained on December 08.41 at V=15.5 and on December 10.52 at V=16.1. We do not detect this object in images taken on 2014 UT December 02.32 and before. There is no Vizier match or previous CRTS data for this candidate. Follow-up observations are encouraged.

ASAS-SN CV discoveries and detections of outbursts from known CVs can be viewed at the ASAS-SN CV Patrol. The website monitors the locations of known CVs from the AAVSO catalog and places a CV in an 'Active CV' table if the latest measurements are at least one magnitude above the reference images. In the Active CVs table we also include new ASAS-SN CV candidates from the ASAS-SN transients webpage. The website is automatically updated in 'real-time' as the goal of this project is to aid observers following up interesting CV targets. The ASAS-SN CV Patrol will also form the basis for other ASAS-SN public 'real-time' data releases.

Currently, the top 3 brightest CVs on our website are: SDSSJ225831.18-094931.7 at V=12.4, 2QZJ015940.6-281040 at 12.8, and TYPsA at V=12.9.

We thank LCOGT and its staff for their continued support of ASAS-SN. For more information about the ASAS-SN project, see the ASAS-SN Homepage and the list of all ASAS-SN transients.
