CRTS continues to detect large number of transients including blazars which
show stochastic activity. Variability at all wavelengths is quite common for
blazars and they can show variations of even several magnitudes sometimes in a
matter of days. Behavior as reported in recent ATels e.g. #6038 (Balanutsa,
2014), #6070 (Shumkov, 2014) is thus not unexpected. Shown below are a few
blazars discovered by CSS and MLS during the last few months. Spectra during
the bright phase are typically featureless.

All transients were discovered in real-time by the CRTS pipeline and openly
published to VOEvent network subscribers (such as SkyAlert). Links to CRTS
transients can be found at http://crts.caltech.edu CSS blazars are
collected at: http://nesssi.cacr.caltech.edu/catalina/AllBlaz.html and MLS
blazars at: http://nesssi.cacr.caltech.edu/MLS/AllBlaz.html.
CRTS has been automatically monitoring
a watch list of 277 Fermi and MOJAVE blazars since 2009.

CSS is funded by NASA's NEOO program. Part of the variability work related to
blazars is supported by NSF grants AST-0909182 and IIS-1118041.
