Predicted event time was 21:05:02 UTC (+/- 4s) for my observing position. Predicted maximum duration was 0.5 seconds with a 5.0 mag drop. Position was 12km from predicted central line in SE direction inside the shadow with a probability of 7.2%. Analyzed by Tangra. Synchronization of Windows system time was by NTP Time Server Monitor(Meinberg), checked by TimeMemo software
