QUASAR PKS 1222+21
V. M. Larionov et. al., (ASt. Petersburg University, Russia) report on 'The
Astronomer's telegram 5921 that they have performed optical photometric and
polarimetric monitoring of the flat spectrum radio quasar (FSRQ) PKS 1222+21
(4C 21.35, z=0.432) using a 0.40-m LX-200 telescope (St.Petersburg, Russia)
and 70-cm AZT-8 (Crimea, Ukraine). During the last month this quasar has
displayed prominent activity. On the nights of 2014 February 24 and 25 it
reached a level of R=13.86 and 13.80, correspondingly. These values can be
compared to the quiescence level of R~15.7 recorded in 2012-2013.
A preliminary optical light curve is given here:

Optical fractional polarization during the outburst is rather modest, on the
level 2-5%. They notice that our analysis of the publicly available Fermi
LAT data also shows enhanced activity in gamma-rays
(http://lacerta.astro.spbu.ru/lc_gamma/pks1222.png).

Stefan Karge, Taurus Observatory (MPC B01) reports photometry on 2014 Feb
24.131UT at magnitude 14.22C.
