Observations of the S4 0954+65 blazar during last night 2015.02.12 (JD = 2457066.4) with the Zeiss-1000 telescope of SAO RAS showed that the object brightened by 0.2 magnitudes more as compared to the previous epoch (ATel #7055). However, intranight variability during 2 hour observational
interval showed a decline trend ~0.1 magnitudes in BVR bands with the almost constant colors: (B - V) = +0.50, (V - R) = +0.44. Most likely, we observing an absolute maximum light of the blazar.
Night-average magnitudes of the object can be found in the following table (errors are given for the single frames).
