We report the discovery of several flaring radio sources and blazars by the Catalina Real-time Transient Survey (CRTS) Survey during the last few weeks. All these were announced in real-time on the CRTS website and Skyalert.

Follow-up images for these and many other CRTS objects from Palomar 1.5m telescope are available at: http://www.astro.caltech.edu/P60FollowUp/

More information and finding charts can be found at http://voeventnet.caltech.edu/feeds/ATEL/CRTS/
All CRTS Blazar discoveries are available from http://crts.caltech.edu/.

We are grateful to the all the observers involved in follow-up observations. Further follow-up is requested. A search for the corresponding gamma-ray flares in the Fermi data would be useful.
