Our own data from 07-2013 and 03-2014 show again some variability $\Delta R \sim$ 0.33 mag,  where the error estimate is $<<$ 0.1     \subsection{1129+3758E2}   NOT ALFOSC ALxa14 (14-01-2014) 2x200+2x300 sec \\   Empty field i>22.3 mag (of the difference).  In optical (R-band) the target is unresolved (FWHM $\sim$ 1 arcsec), however the  images are not deep, ruling out only very low redshifts ($\le$0.05) assuming that the   object is a typical blazar.
