The field of the blazar [HB89]1633+382 was observed with the 1-meter telescope Zeiss-1000 of the Special Astrophysical Observatory of RAS (Caucasus, Russia) equipped with UBVRcIc filters and a 2k x 2k EEV 42-40 CCD. The observations were performed in the Rc filter. We detected the strong optical outburst noted by Danilet et al. (ATel #6930) and Arkharov et al. (ATel #6942). Our conclusion is based on the photometry of the object during the last two months.
