Explanation:
This spectacular sky is mostly human-made.
Once a year, the
Light
Station at Pigeon Point near
San
Francisco,
California,
USA
is lit as it was over 100 years ago.
During this time, light generated by five
kerosene lamps
pours through 24 rotating
Fresnel
lenses,
warning approaching ships to stay away.
Early last week, light emanating from the Pigeon Point Lighthouse was
particularly
picturesque because of a thin fog, also blurring
the distant Moon.
During the latter 1970s, the
lighthouse
was guarded by an 800 pound pig named Lester.
In modern times, the light house is still active but has been supplied
with a
more
efficient flashing
aerobeacon.
