    Perfect night for the occultation.

    From here near Southend in Essex the occultation lasted 9.1 seconds starting 04:28:05.7UT I will check my results when I’m more awake!

    From Edgware the occultation lasted 14.7s from 04:28:09.5 to 04:28:24.2.

    I’ve placed the time-stamped video on YouTube

    Got back from France at 10pm last night and woke at 4am. Sky here suffered from high misty cloud with one or two clearer patches. The cloud made the sky very bright within 10-15 degrees of the Moon. Since the main observatory is ‘hors de combat encore’, I would have had to use a tripod-mounted 4″ short-focus refractor to observe, but from experience I was convinced I would never have found the star in question. With a telescope of 10″ aperture or more, it might have been possible. Looking at the track of the shadow, the location here in Dorset would have been very close to that of Tim Haymes and David Arditti so not a great deal lost in the event. Congratulations to those two folk and to Peter Carson for their positives. Not easy!

    Was keen to have a go at this, so went to my observatory at about 5am to set up. Firstly my mount wouldn’t connect to my laptop. Eventually fixed this. Then the batteries in my controller went. Fixed this. Then my laptop froze. After a short period of mild pandemonium I fixed this also. Anyway, after the dust had settled I checked my timings relative to others and think I missed the end of the event by a matter of seconds! Next time I will double check everything and give myself more time. Enjoyed it anyway!

    11 minutes before the occultation I took this image showing the field around HIP 14977 with 275 Sapientia just about to occult the star.

    The 12 observations from UK are on EURASTER.NET. What a great night and great result for UK observers ! The profile of the asteroid can be seen on the link to chords for Sapientia.  Peter Carson’s observation is chord 15. 

    My video is also on YouTube  https://www.youtube.com/watch?v=j0lpfz_S5Js

    Congratulations to everyone that observed this event – indeed an excellent result!

    I enjoyed your Youtube video, Tim – thanks for posting. It looked to me that there were a couple of flashes towards the end of the occultation – was that due to the seeing?
