Viewed today's annular eclipse here in mid Missouri.....always gives me a
thrill to teach about the pinhole camera and be able to demonstrate on
such a grand scale.  About 1/2 through the eclipse the class noticed a
strange phenomena.....shadows, normally sharp in the sunlight, became
two....that is two shadows one darker than the other occured with say a
pencil ...... one explanation--each part of the sun still visible was
casting its own shadow...but there was no discontinuity in the sun-just a
half ring sorta...again(for the gazillionth time in 30 yrs teaching
physics) I admitted I didn't have an explanation.
