[pct-l] Rare astronomical events for 2012 hikers

[Robert Henry]

Here are two astronomical events, one rare, and the other very rare,
that will be visible along parts of the PCT in the 2012 hiking season.

There's a total solar annular eclipse on May 20, with path of maximum
occlusion in NE California (this will be too early for the thrus).

There's a transit of Venus (across the sun) at sunset, June 5.  See:

NEVER look at the sun directly, even through glacier goggles.  Set up
a pin hole projection camera, or equivalent; see
