We present CCD opbservations of BL Lacertae obtained from August 1997 to August 1998. The maximum amplitudes in BVRI bands during observing period included most part of great ouburst and second one are equal to 3.00 (rms=0.03), 2.71 (0.02), 2.53 (0.01) and to 1.25 (0.040), 1.11 (0.03), 1.02 (0.01) 0.91 (0.03), respectively. The amplitude for variability is larger toward the blue end of the spectrum.
