"To the moon, Alice(Elon)..."
There is a combination lock park staff kindly provided for us.
The gate is often dummy locked (but not always). I can provide
the combination off-list, it changes monthly.
The June 30th note (below) states 11:34am, the event is PM.
About the overflow lot - from there the true eastern horizon (0° alt) is obscured by a
ridge running east to north, "delaying" visible moonrise. The
moon's azimuth rising the 4th at 23:34 is 72°.
It might be possible (not certain) to view from the campground
parking areas - but I think that's chancy. Maybe try the backside
of Mt. Hamilton on Hwy 130? I've never been past the observatory,
so its a guess. Or park near the observatory entry road and walk
up, it may be visible - I think the eastern view is clear to the
Sierra from the backside of Lick.
Will this event make Elon mankind's biggest solar system
litterbug? Should he be sent to clean up his trash?
