The circle above is plotted at the expected diameter of Notburga. The circle has been plotted to fit the observed chords as far as possible. With the high levels of integration required, and the brevity of the event, the durations must be considered approximate.
The figures below show the Tangra light curve of the occultation.

A long integration period (32 frames) required to maintain visibility of stars through cloud.
Apparent R was 1 integration period was evident although a duration of 2 integration periods would be expected. Reported duration of 1.3 seconds based on 1 integration period _______________________________ Observer W H Allen Location Blenheim Longitude +173:50 Latitude -41:29 Altitude 38 m Datum WGS84 Telescope SCT including Cass and Mak Aperture 40 cm Seeing Steady Clear Camera Type Watec 910BD NTSC/EIA Camera Delay Timing GPS - time inserted Video with frame analysis Disappearance 09:15:53.01 Reappearance 09:15:55.65 Comments: _______________________________ Observer G Hudson Location Porirua Further observational details not currently available. Missed Comments: Further details not provided by the automated system.
Although an apparent light curve was produced, on further analysis this was considered to be a miss.
