Predicted event time was 22:34:15 UTC (+/- 10s) for my observing position. Predicted maximum duration was 4.6 seconds with a 0.7 mag drop. Position was 133km from predicted central line in SW direction inside the 1-sigma limit with a probability of 10.0%. Receiving 07 satellites Horizontal Dilution of Precision 1.1
