The Occultation by Kapteynia - Dec 1, 2010

Here's the Preston prediction link. This occultation happened smack in the middle of Astro 9 class. It was indeed clear, and so it was hectic getting the astrophotography setup's up and running, getting students in charge of taking photos, and then getting 45 minutes relatively undisturbed to set up the 10" scope, find the star, and try and record it. The predicted path was off the coast a bit, but only a reasonable north shift would give an occultation so it was well worth a try. There was no moon, and the star was situated inside a tight little line of 3 stars making detecting an occultation easier. Now, I did something very absent-minded and was a first for how to blow a viderecording. I got the 10" set up, flipped the "on" switch and saw the red power light come on for a split second and go dead. Damn! Did this scope just die AGAIN?! That's what I figured. I realized I could still track the star manually with the slo-mo controls but then I'd have to do it visually. And that's what I did. The predicted moment came and went and I figured I had a miss, as the calculated path suggested - and just then the star winked out. I shouted "D!", and one second later it was back "R!". The event was predicted to last 4.7 seconds for a central event, and mine lasted 1.0 seconds, and was 5 seconds late. Here's the .xls report. and Timerson's reduced observed profile
