Norcatur, ~s., sky explosion
of lS February, 1946
To shc,,r a speculation regard
ing tho above phenomenon and
another one of earlier date
and to call attention to
occurrences between the two
which have an appearance of
relationship whether coinci
dental or not.
The geographical position of the Norcatur explosion s uggests poss ible
linka.!;8 with other occurrences happening inside latitooinal limits arbitrarily
demarkable between 43° 36 1 North (which is the latitooe of Ooise, Idaho)
and 36° 101 North ( the lati tu:ie of Nashville, Tenn.)., a belt about 485
miles wide.
'lbis suegestion is gained from positions given for occurrences
happening between June 24., 1947 and February 18 , 1948, as s hall be
hereinaft er briefly described,
THE OOISE (Idaho) OBJECT- This was seen either beginnin{.! or ending at 330 pm
24 June 1947 am was visible for 20 minutes. It was in the western sky,
was of comet-li~ appearance, and settled gradually toward the horizon ae
planetary bodiea set. It was seen bo.r Lt. Gov. Whitehead •u)j Chief Jus tice
Lartpert. Its nature was unknmm .
The peculiarity which connects this object, for speculative purposes, with
the explosion of some unknown object over 1~orcatur, Kans ., on 18 l!'ebruary
1948 is the seeming of a relationship between the positions of the moon for
the two phenomena:
In the form2r case the moon was at the date of phenomenon, about 7%, 63
before the positionof First Quart er; on the second case i t was about 8%. 73
beyotxi the position of first quarter.
Since the Boise object was visible for 20 minutes be fore it sank this
argues it was about ten deil"ees a bove the horizon when fi?1J t seen. Now
