  The region of SGR 1806-20 localization was observed during its gamma-ray
activity in 2001. The observations have been performed on the 6-meter telescope
of the Special Astrophysical Observatory, using the Panoramic
Photometer-Polarimeter (PPP). The search for variability was performed on the
$10^{-6}$ - 10 s time scale, and its results were compared to the properties of
corresponding x-ray flares.
