The path runs parallel and on top of the San Andreas Fault defining the spine of the Santa Cruz Mtns, and Highland / Summit rds. It's low in the SE, rising, at only 14 degrees, so getting a clean low horizon is critical. Karl's out of state, so perhaps just me, and Kirk I hope. I'm planning on trying it from a spot on Rodeo Gulch Rd where I watched an occultation of Antares years ago, so I know there's a spot with a good horizon in that direction. Odds of a 'hit' there are 72%, better as you go north, up to 85% on the centerline.

 

   

Results:

I changed my plan at the last minute, wanting to up my odds and probably not lose time; and drove up to the Mountain Charlie monument at the top of Hwy 17/Mtn Charlie. It had a good view, and I got a good 2.7 second occultation.

Here's my reductions, using PyMovie and PyOTE

As usual, my IOTA Excel report is on my computer under the AstOcc folder. To save website space, I'll not upload it here. It's been sent to IOTA As of June 17, 2021.

Observers in Arizona including Paul Maley planned to get this one too - but heavy smoke and flames knocked out their efforts. The fire season is starting out with astronomical casualties.
