Post-Graze Results
Big success! The twilight did not interfere much with the video recordings for me or Chris Angelos, or Allen Ginzburg. Very mountainous profile was dead-on where predicted and produced a nice graze. All of us got good video-taped accurate timings: Allen had 2 events, I had 13 events, Chris Angelos had 8 events. Our timings are on a separate report page.
My station, next to a barn at the foot of Meadow lane, lit here with a security light on the barn roof |
Chris Kitting's station, dutifully occupied by Chris even though he arrived 10 minutes too late to get the graze. We chatted about his recent NASA mission and I advised him on image processing ideas for his data on that mission. |
Derek Breit's group in Morgan Hill also had a great success, and this will be one of the best observed grazes in California this year.
OCCULT 4 produced this plot of the timings for the Aptos team. Unlike the planning page profiles, this reduced profile has "sealevel" on the moon as a straight line and the star path will then be a section of an ellipse. I'm just a bit north of Chris Angelos. Chris is next, just getting a peek of the star in the valley at WA=165, which produced so many events for me. Allen was far enough into the moon to miss both valley bottoms and just get a D and R. The timings agree beautifully, Kiwi time inserters make guessing about reaction times a thing of the past! |
Derek Breit produced this plot which includes all observers, including those in Morgan Hill. Morgan Hill observers were a little north of my location and got more multiple events in the WA=165 valley. Also note that the WA=159 mountain has a flat top ~parallel to the star track, and not the peak top shown in the Watts data. |
