MASTER-IAC pointed to the IC 171106A at 2017-11-06 18:41:11UT 91.8s after trigger time.
The Sun_Altitude was -5.64, and so as MASTER-Kislovodsk and MASTER-SAAO followed up alert observations,
MASTER-IAC followed Fermi inspection after sunset, and followed IceCube inspection on next day by usual inspect program
