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 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 ($\la$0.05) ($\le$0.05)  assuming that the object is a typical blazar.  Our optical lowresolution spectroscopy suggest that the target is a BL Lac object.
