Ref: Case: 24 Nov. 1955
Hokkaido, Japan

The sighting of a red glow was reported as of 16:13 Z at Long. 140° E. and 52° N, on Nov. 24, 1955. Glow reported to have been low on horizon, at equinith (bearing) 312°.

78 yrs of interest to complete the equinith of the gibbous moon at that instant (16:13 Z) at Hokkaido.

For this purpose, we note that at that time the right ascension of moon was approx. 23° 32", and its declination, approx. + 2° 42'.

Computation shows that the local sidereal time at Greenwich at C.C.T. 16° 13" was 20° 24".

and at Hoboken it was therefore
5' 48" The hour angle of the
moon (t) was therefore 6' 16"

To obtain the age in with of
the moon, we employ:

$$
\text{tan } \hat{z} = \frac{\sin t}{\cos \varphi \tan 5 - \sin \varphi \cos t}
$$

where
z = age in with angle
t = hour angle of moon
φ = latitude
δ = declination of moon

Making the proper
substitutions we find that,
tan z = 1.180 (approx)
z ~ 49 1/2 W.

The age in with A is therefore
360 - 49 1/2 = 310 1/2
Since the reported bearing was
312°, it would appear that

the glow and the position of the
setting moon* at that time
were identical within
allowable errors of observation.
Moon set at Hokkaido that
morning at approx 2 A.M.
Local time of sighting was
1:37 A.M. The moon
was, therefore, about & set.

Further substantiation of
identity of object sighted
with the moon is hardly
needed, but it can be pointed
out that at moment, as is the
sensest case for senset, the
atmosphere causes the moon
to appear quite red. Further
as is also the case with the
setting sun, atmospheric
refraction causes the moon &
appear somewhat oblong in
shape.

AT APPROX 01131 CMM LOCATION WD 6560 CMM ALTITUDE 25,000 FEET AND ON HEADING OF 360 DEGREES. I BECAME AWARE OF A RED GLOW TO MY LEFT. AT FIRST IT APPEARED TO BE A REFLECTION FROM THE COCKPIT INSTRUMENT LIGHTS CMM BUT I ELIMINATED THAT POSSIBILITY BY PUTTING MY HAND AGAINST THE CANOPY AND PEERING THROUGH TWO SPREAD FINGERS WITH MY HEAD AGAINST MY HAND.
