This event is on the short list of IOTA Campaign events, and so should attract a good number of observers. Kirk Bender, I, Dave Gault, and Peter Nosworthy were the 4 who discovered and confirmed the binary nature of this asteroid, and refined positioning will refine the masses and densities of these objects.
Here is a small scale US map of the path
The moon is 78% and 89% on Fri night and Sat night, so not good for an Astro 25 weekend, but it's a weekend, and high value, and so I hope that Kirk and I and perhaps another person or two to man our other occultation rig, can do this from the desert again.
