YouTube Video of the occultation.

The event was recorded with WAT-920H camera. This was my best event so far. Magnitude 7.4 star with a 3.5 mag drop so the asteroid remains visible during the occultation and a duration of 26 sec. I had a lot of luck for this one. There was a lot of cloud before the event and the target was fully clouded just 5 min before the event. There is also some thin cloud during the occulation as seen from the light curve.

Catalog comparison. All catalogs except UCAC3 were in agreement.
