The occultation of a star by asteroid Deiphobus (1867) - 17 November 2011

Another positive occultation of a star by asteroid. Althouth I was out of an expected shadow line I managed to catch it.

I found all necessary information and maps on the web site www.asteroidoccultation.com.

The path was calculated as it is shown in this picture.


From store data it is clear that the start of occultation was at 17:20:15,984 UTC +/-0.15s; the end was at 17:20:22,484 UTC +/- 0.15s. The occultation duration was 6,5s +/- 0.3s.

I was watching the whole phenomenon in real time on screen in warmth of my wooden cottage with my wife and my son.
