A TOTAL
ECLIPSE
MOON TO HIDE ITS FACE
TONIGHT
The First 0ccurance In Four
Years

ing, if weather conditions are favor,
able, Carsonites will be afforded the
opportunity of witnessing one of the
rare and interesting phenomena of
the solar system, a tota. eclipse of |
the moon. For that length of time |
the earth's satellite be, blacker than |
Carson's streetss, when one of the |
frequent breakdowns occurs in the |
electric power houses. For several |
hours longer the bright orb will be |
in a semi-shadow that will make it |
lock as if it were hiding behind a
black veil. The moon will pass al
| most centrally through the earth's
| double light and black shadows and
if there are no clouds the interesting
phenomenon will be plainly visible
to the naked eye of people in almost
every part of the Unietd States.
The eclipse is the first total one in
four years, and it will be observed
with much interest by the astronomers
and laymen interested in that kind
of phenomena, wherever it is visi-
BILE.
Considerable interest is being ma
infested in the coming eclipse and it
is expected that much valuable infor-
nation will be gained by the stu
dents from visual study of the real
happenings.
! Begins in the Evening.
The eclipse will commence at a
little after s o'clock in the evening
and last until nearly o'clock in the
morning. OF course, the greater part
of this time the moon will be only
partially obscured, it being then in
the semishadow cast by the earth,
but for an hour and half it will be
totally dark.
, The exact time of the different pha-
SEES of the eclipse as calculated for
: local time are as follows:
, Moon will enter penumbra SIT
r p. m. Oct 16
Moon will enter umbra, 9:17 p. m.
Oct. Is.
, Total eclipse will begin 1919 p. m.
r Total eclipse will end HAS p. m.
Moon will leave umbra, 1880 a.

l = The moon, as is known, shines only
f with the reflected light of the sun
and total eclipse is nothing more
:. Or less than the shutting Off of the
v moons supply of sunlight, caused BY
e the moon getting behind the earth
t. For these conditions to be brought
e about the moon must, of course, be

J. and in such a position that the lin,
e earth is directly in the line of igh1
e from the sun. This happens when the

Details Of Phenomenon.
=, The earth being round and the SUI
u many times it's size, the dark SHADOW
Il, O. the former is in the form of
"a cone tapering away from the eartf
u This dark shadow is called the umbra
G Outside of this black cone and SUI
N rounding it is cone of semi-shadov
~ diverging from the earth off int
y space. This cone marks the ZOn
le from which only a portion of the sun
rays are shut out by the earth, an,
IN this is known as the penumbra, {
ie light shadow. When the moon is
this zone it's brilliancy is very muc
dimmed, but it still shines. It is OF
es ly when the moon passes into the blac
nj cone that it is intotal darkness /
reality it cannot be said that it is
total blackness then, for it's soutliI
nt is marked by dim cOpperish ting
II, resulting from the refracted rays
he sunlight that fall upon it, The cope
IL ish tinge of this light is produced
the atmosphere of our own. cart
ne which possesses the property of dist
Ike tegrating the rays of light and absor
on ing the colors except the red. IN,
the outline of the moon is visib
throughout the time of the tot
"n eclipse.
of Duration Will BE Long.
on The duration of an eclipse, of cour
~. depends upon the point at which t
moon passes through the black sh
60 dow. Upon this occasion the mo-
on will pass through the center OF Il
Of shadow where the diameter of t
, cone is several times that of the moe
'n' and the period of total eclipse W
ats be correspondingly long. When t
lit moon begins to enter the cone
he black shadow, black arc, which
one of the proofs of the earth's spl
rical form, will appear upon the or
ne ish disc of the moon, and gradua
sed grow larger until the entire visi1
ALL disc is consumed in darkness. AS I
-. moon emerges from the dark shad
&c" the reverse will be true.
ade From the fact that the earth mi
oe- be between the sun and moon fol
tn total eclipse to occur, it is easily S,
that one can occur only when
nas moon is in the phase known as I
nds moon. The reason that there is
ion a total eclipse every time there i
,ec. full moon is that the moon trav
