Our adventure was headquarter'ed at Honeymoon Flat campground, by the East Walker River. It was a perfect campsite, with wide views of the sky. Fred and Jim had staked out a good place by the time I arrived at 5:30pm. The rest of the gang trailed in as I set up the scopes and turned the students towards the task of starting our pasta dinner. The graze was our big goal #1, but our clear skies suddenly showed some clouds over the Sierra crest, right where the moon was. Still, it remained clear around the moon for a while, long enough for Diane to watch her first lunar occultation, of a 7th magnitude star a few minutes before the graze. But clouds engulfed the moon minutes before the graze itself, and didn't clear away till 15 minutes later. Our two stations were totally shut down!
