Dear Dr SE.

Sontact was nade with the various weather stations to determine
the weather 4% the time of your sighting and Salloon lsunching schee
ules. A rawiasonde is released dsily a’ 1500 hours from the Wetro-
rolitanmn Oaklaad International airport. ‘The prevailing winds on 14
December 1553, at che time of your sighting would have drifted a
balloon, released at this airport, to a positicn corresnoading to

Yhese bailvona attain diameters of greater saan 30 fset at altie
bude aad Lave 3 relatively nigh albeto. This xvact ia aubdstantiated
by your observation that the object was brishter than Venus, which
hag 3m apparent magnitude of -4.j at ita brightest. These dalioconsa
ere aiso saquipped with radar reflesters which could possibly account
for the amaller od jects.

Attention: AFCIN-E}
Dear Sir:

Referring to attached letter, also please refer to Aviation ‘Week issue December 22,
1958, page 2h, which reached me after my letter dated December 23, 1958.

If the Thor firing from Veandenburg was on Sunday, December 1h, 1958, and if it
were delayed more than "scheduled at about noon but did not come off until about
three and a half hours later", we can button this up,

If it were not the Thor firing, it was something else anda I answer your queries:
1. Magnitude comparison made es’follows. I have always had to search to
find Venus in daylight at greatest brilliancy. This primary object was
so visible it caught my eye immediately as well as my wife, without my
heaving to point out its direction. I used Venus in daylight at greatest
brilliancy as the bese for determining the, magnitude.

2. I thought at first it was reflected light but after reading the Aviation
Week report I note a reference to a "white hot exhaust",

3. Color was that of Venus, streak more yellowish. At present time (6 weeks
after) I would guess streak color about that of Arcturus. No pulsations,
no shock diamonds, no flickering. There wes a steady fade, however, but
also a steady increase in high thin overcast as I stated.

h. Unable estimate angle subtended--too small and too unsteady through
binoculars. If necessary I can amend this statement by setting uo a
trensit and getting an idea using the Radome on Tamalpais, and inter-
polating into the binocular field. Let me know if you wish me to do

FURTHER COMMENTS

—

Tf I accept the Aviation Week statement then how do I reconcile the Thor firing
stated azimuth of 251 degrees? Take my estimate of 135 macnetic, edd variation
and pive me 20 decrees of error and JI get an ansver of less than 180° true from

Berkeley half a mile west from Claremont Hotel.

This sichtineg I made was definitely east of my meridian. I must assume that you

heve distorted the Thor firing azimuth prior to publication.

Aviabion Waek mentions two verniers. I must have seen three snall objects or I
wouldn't ha e

7 ve described three. I attach my orisinal data sheet ‘a
course, »D

bs which were, 0:
raphrased for style and gramnar to make my report.

If you can, without violating security, let me know if both I and my wife doped
off tocether. We are botn pilots and had neither been drinking or in any way
not in full command of our senses and naturally we're curious.

Please return my original data pages after you are finished with them, Thanks.
