Did anyone else see the Aldebaran occultation mentioned by Stewart in his news article here? After a really nice day here in Chelmsford it clouded over for the disappearance at the dark limb but was much better an hour later for the reappearance at the bright limb. I made a short video using a Celestron C6 and a Canon EOS550D which you can watch here. Just before immersion you can occasionally see Aldebaran through the cloud but it actually goes behind the moon when it is invisible behind cloud. At emmersion the seeing is pretty poor so it is quite difficult to detect the first appearance of the star.
I watched ingress, Nick. Always impressive to see a bright star like Aldebaran suddenly disappear behind the dark limb – you get a real impression of the moon moving against the background stars. I was clouded out for egress, though.

In recent weeks the weather has been cloudy, cloudy with rain, or clearing and blowing a hooley, so it was a pleasant surprise to have a fairly clear sky and occasional light breeze for recording and timing the D and R events.
Clear skies,
Alex.
Thanks Jeremy.
I’ve observed a few Aldebaran occultations over the years, with varying success. On 1979 Jan 9 I observed and timed a DD and RB pair, using a stopwatch and time signals. Modern video systems and techniques allow us to obtain much smaller O-Cs than in the days of manual timings, personal equation, etc.
Clear skies for 2016.
Alex.
I’m late to this thread because of the Christmas break, but I’m glad that some members were able to catch the occultation. I had all the meteorological conditions described by Alex, apart from the ‘fairly clear sky’ bit…..
Some Lunar Section members have already submitted timings, but I’d be glad to receive further observations of the event.
May I wish you all clear skies for 2016!
Bill
