A Perseid Meteor Fireball
A Great Perseid Meteor Fireball in Annual Meteor Shower
This black and white photograph of an extremely bright Perseid
meteor fireball was taken on August
13, 1966 with a Zeiss-Ikon 35mm camera using a 35mm f/2 wide angle lens
and Kodak Plus-X film
with an ASA of 80 pushed to 160 in the darkroom. The camera was mounted
on a fixed tripod, and
the exposure was over an hour long. The zig-zag irregular appeanance of
the meteor and star trails are
caused by the scanning and sizing of the image to the page.
This night I was taking long exposures, since the previous night I had
taken exposures of 5 minutes
before I would advance the film and re-point the camera. It seemed like
everytime I changed the
exposure, and/or pointed the camera in a different direction, a bright
meteor would go through the exact
field I had just moved from!! Very frustrating, indeed. I suspected leaving
the camera in the same position
for extremely long times would yield better results. The above photograph
was a real piece of luck...
just as I got ready to end the exposure, this -12 magnitude fireball streaked
through the camera's field
of view. The fireball was equal in brightness to the full moon. This was
the third fireball seen of this
brightness...the first seen was in Portland, Oregon, in 1950...the second
was seen in Seaside, Oregon
in 1958.
Most meteors seen in the night sky are the size of a grain of
sand! Brighter meteors are the size of a pea,
and the one pictured here could be the size of a golf ball or larger. When
this bright, occassionally
some fragments may reach the ground...and even some have been found after
such displays.
Table Mountain Observatory, operated by the Jet Propulsion Laboratory (JPL),
is located just west of the
town of Wrightwood, California at an elevation of 7500 feet.
