This is a bright, long event and Cabrillo 800 building is decently inside the northern limit of this high'ish rank event. Odds are good for an occultaton and good data. The path does not cross Santa Cruz nor Karl.
Alt=44, Az=190 in Aquarius. 10 degrees below "the Tripod" asterism
This should be nicely visible from the utility road next to classroom 806 where I'll be teaching Astro 3-2. I will have to start our mid-class break quite early and then resume teaching afterwards after a quick re-pack of my RAV4.

Karl and I tried this one.
8pm is during the mid-class break in my 3 hr Astro 3-2 section "Solar System Astronomy" at Cabrillo College. I parked the RAV4 outside the classroom, and at 7:30 set up to get the occultation. I had a half dozen students join me and they watched as the star indeed disappeared for about 1 second at the predicted time. I recorded at 4x. Visually, my impression was that the star also blinked completely out for a moment about 1 second before the main event. We played it back in the classroom on the Lenovo computer and others watched and also thought it winked out briefly just before the main event.
Reduced: The pre-event blink is on the light curve, but it's not complete to zero, and it's only a single integration, and there are others on the dynamic mask light curve. It's probably noise.

Karl and Carla drove to Ormsby Rd and Highland Way to get inside the path. Clouds, unfortunately, hid the star till too soon before the event, and got no data.
