Abstract:
We present the earliest astronomical observation of a high-energy
neutrino error box of which the variability was discovered after
high-energy-neutrino detection. The one robotic telescope of the
MASTER global international networks automatically imaged the error
box of the very high-energy-neutrino event IceCube-170922A.
Observations were carried out in minutes after the IceCube-170922A
neutrino event was detected by the IceCube observatory at the South
Pole. MASTER found the blazar TXS 0506+056 to be in the off-state
after one minute and then switched to the on-state no later than two
hours after the event. The effect is observed at a 50σ
significance level. We also present own a unique 16yr light curve of
blazar TXS 0506+056 (518 data set).
