4C+28.07 still brightening
Abstract
We continued our monitoring of the blazar 4C +27.08, after the Gamma-ray flare reported in ATel #3670, with the 23.5cm TACOR telescope of the Department of Physics at La Sapienza University and the 31cm Newtonian telescope of Greve in Chianti. The TACOR uses an Apogee U2 CCD camera with a KAF1603 chip and a standard R (Cousins) filter; the Greve telescope uses a DTA CCD camera equipped with a back-illuminated SITe SIA502a chip and V, R and I (Cousins) filters.
