  We present the results of observations obtained using the MASTER robotic
telescope in 2005 - 2006, including the earliest observations of the optical
emission of the gamma-ray bursts GRB 050824 and GRB 060926. Together with later
observations, these data yield the brightness-variation law t^{-0.55+-0.05} for
GRB 050824. An optical flare was detected in GRB 060926 - a brightness
enhancement that repeated the behavior observed in the X-ray variations. The
spectrum of GRB 060926 is found to be F_E ~ E^-\beta, where \beta = 1.0+-0.2.
Limits on the optical brightnesses of 26 gamma-ray bursts have been derived, 9
of these for the first time. Data for more than 90% of the accessible sky down
to $19^m$ were taken and reduced in real time during the survey. A database has
been composed based on these data. Limits have been placed on the rate of
optical flares that are not associated with detected gamma-ray bursts, and on
the opening angle for the beams of gamma-ray bursts. Three new supernovae have
been discovered: SN 2005bv (type Ia) - the first to be discovered on Russian
territory, SN 2005ee - one of the most powerful type II supernovae known, and
SN 2006ak (type Ia). We have obtained an image of SN 2006X during the growth
stage and a light curve that fully describes the brightness maximum and
exponential decay. A new method for searching for optical transients of
gamma-ray bursts detected using triangulation from various spacecraft is
proposed and tested.
