8.ADDITIONAL COMMENTS:
        Target star TYC 1682-00072-1, +11.0mag, 51deg Elevation.
        Only Clear glass filter (Astronomik) for CCD protection was used.

        Video evaluation accomplished with VirtualDub 1.10.0, Tangra v1.4.0.499

        Event data details according to the predictions from IBEROC.
        Predicted event time was 23:14:27 UTC (+/- 7s) for my observing position.
        Predicted maximum duration was 19.6 seconds with a 1.0mag drop.
        Position was 57km from predicted central line in NE direction
        between center line and path edge with a probability of 62.9%.
        No occultation event detected (It=0.080s).
