a flat glass filter before the lens in the conventional position produced additional
flare spots, which moved about with slight variations in filter orientation.

2. Flare images are always encountered in photography when on unuevally

ADAK, ALASKA
1l September 1950

On 11 September 1950 at 4:45 pm, a Coast Guard photographer
took four photographs of the total eclipse of the Sun, whose path
of totality crossed the Aleutian Islands near Adak, Alaska. The
photographer noticed nothing at the time when he took the pictures.
It was two years after the photographs had been taken that the

observer noticed the images on the film.

The photographs were examined and the probable cause determined. .

A 4" x 5" Speed Graphic Camera with coated lens was pointed toward
the sun, and the image was examined on the ground glass. A pro-
nounced flare spot, in addition to the main image, was noted with the
lens wide open, f/4.7. Any camera movement caused the flare spot to
move, as well as the main image. Inserting a flat glass filter before
the lens in the conventional position produced additional flare spots,
which moved about with slight variations in filter orientation.

Flare images are always encountered in photography when an
unusually bright object is included in the field of view, and when the
_ exposure is not proportionally reduced. The stated exposure is con-
siderably in excess of normal for an object as bright as the sun, as
shown also by considerable halation of the negatives about the sun
images.

It is probable that the spots in question are nothing more than

flare spots due to overexposure for sun brightness.

Washington, D.C. WASHINGTON, D.C,

Subject: Four Photographic Negatives, showing images of the Sun in partial
eclipse and in addition, unidentified images.

le The enclosed subject negatives were exposed under the following conditions:

a) Camera; 4 xz 5 Speed Graphic

bd) Lens; Kodak Ektar, COATED, f. 4.7, 127mm

c) Film; Kodak Super xX, film pack

a) Filter; Wratten "A"

@) Bxposure; 1/100 sec. at f. 22

f) Place; From the weather deck of the U.S. Coast Guard Cutter NORTHWIND
‘ in the Bering Sea about 40 miles north of Adak in the Aleutian Islands

@) Times; About 1600 hours in zone “plus eleven"

h) Date; Total Eolipse of the Sun in the summer of 1950, whose path of

totality crossed the Aleutian Islands near Adak Alaska
1) Developed; 6 July 1952 in Kodek Microdol, 13 mins at 78°F

2e These negatives bear the pack sequence numbers 2, 3, 4 and 5 and when viewed
with the clipped corner held to the lower left, the eclipse images were exposed
from left to right and from top to bottom, at fairly uniform intervals of
approximately 30 seconds each.

Se It is apparent that the unidentified images to the right of the eclipse
images are all of the same object, but vary in size, shape, attitude, altitude
and distance from the eclipse image in each case. The possibility that they
have some simple explanation in optics or meteorology has been considered
carefully and in view of the inconsistencies mentioned were deemed worthy

of being forwarded for expert sorutiny.
