Here is the observed timings of Nolthenius and Ginzburg, also plotted with +-0.3 deg libration previous occultation data. South is up, and horizontal is the "sealevel" lunar surface, so the star path is an ellipse opening upward. Our observations match the Watts data nearly perfectly, but poorly to past observations. I suspect its a problem with the Watts angle somehow. Plot generated in OCCULT 4. |
Station 1: Allen Ginzburg. Set up in his driveway on Viewpoint Drive in Aptos. Used camcorder and WWV and software to correlate the second ticks and the events.

Station 2: Richard Nolthenius. I set up at the foot of Meadow Drive, behind the barn on the corner. Weather was perfect and all went well. The times below assume half light corresponded to the event, from the Kiwi time stamped camcorder DV recording.
