The diurnal variation of the probability of the appearance of the

PERIODICAL: Geomagnetizm i aeronomiya, v. 2, no. 6, 1962, 1107 - 1112.
TEXT: The authors investigate the probability of the appearance of the--
commencements, the active periods and the ends of magnetic storms on the basis
of,the Irkutsk Storms Catalog for 1905 - 1917 and 1925 - 1959. The catalog
describes 820 storms. A total of 539 of them are storms with a gradual commence.

dinates.in curve 1 represent the frequencies of the commencement of the a-storms)

equivalent amplitudes R'. Similar distinctions between Sa and Snb were also
observed at all other stations. These data, characterizing the phases of the
maximum of the'first harmonic of Sa and Snb, are presented in a table. The
authors explain these results.by proposing that;Snb may be?considered as`a re-

suit of Sa. It is followed that the probability of a'contact of the corpuscular.
flux with the Earth does not depend on the time of the clay. This. conclusion is
confirmed by the fact that, according to the mentioned catalog, the diurnal
variation of the frequency of SC practically does notf,exist. The authors then
investigate the total of all storm days and introduce?,the following'four hypo-'
theses-.:',1) The probability that there is a contact between the flux and-the
Earth,. causing the storm is equal for all hours of a day. 2) The magnetic ac-

of the Scientific Research Institute of Terrestrial gne_,
the onospYere ,and Had lo wave ropaaation
A station was set up on 01'khon kal to make
uninterrupted recordings o short period Pc (steady) oecilla ions
in the terrestrial electric field using equipment with a sensitivity
(0.02 mv/km/mm) higher than had hitherto been possible. It was
thus possible to record to oscillations of a very small Intensity,
The station operated constantly from 10 Sep 1955 to 17 May 1957.
The length of the east-west pickup line was 1000 m, while the
north-south line was 500 m. The observational data obtained,
chiefly on the daily distribution of Pc oscillations, provided in-
formation on the characteristics of short-period oscillations, the
terrestrial electric field, and the influence of the screening
properties of the ionosphere.
Of 322 days examined 288 (89.5%) had Pc oscillations. The
minimum number of days without to oscillations was noted in March
and September, while the greatest number occurred in February and
July. Daily to distribution has the highly pronounced form of a
simple wave with a daytime maximum and a nighttime minimum. A
slight shift in the time of onset of extremal values from winter
to summer was observed. In winter the greatest number of steady
oscillations are observed at 14-1500 hours, while in summer, at
12-1300 hours,lopa1 time. The amplitude of the daily Pc curve
during the equinoctial periods is somewhat smaller than at other
times of the year. The Pc excitation frequency in the period of
least development (00-0300 houre,local time) is about three times
lose than the frequency of appearance in the period of maximum de-
velopment of these oscillations (11-1500 hours, local time). Com-
parison of to distribution curves according to the value of the
period shows that in the equinoctial months the predominance of
Pc recurrence with a period of 20-30 sec over to with other periods
is noticeably higher than at other seasons of the year. Results
did not resolve the question as to whether the short period oscil-
lations are excited simultaneously throughout the world (a view
held by V. A. Troitskaya) or whether they occur according to local
time (the view of R. A, Zevakina and V. V. Kebuladse). In some
cases they Uzur station reported Pe excitation time to occur at
intervals established by Troitskaya, while in other cases the ax-
citation was connected with local time.
The Uzur station could find no direct relationship between
the daily distribution of the frequency of Pc appearance and the
screening of the earth's surface by the ionosphere, since the
most intense Pc and most frequent short period oscillations are
observed at hours when the greatest screening action of the ionos-

tand that their excitation iteconnectedlwithoupperoatmosphericre$s

In the summer of 1955 simultaneous recordings of short period
oscillations were made in guy and on Ushkaniy Island. Processing
of the records by the conjugate ellipse method showed a sufficiently
steady relationship between Fc components in the form:
u - ax + by, v - ex+dy
where x and y are the Pc components on Bol'sho Ushkaniy Island and
u and v are the Pc components in Zu , Comparison s owe a e
Fe amplitude on Ushkaniy is about 12-25 times greater than the am-
plitude of the same oscillation in Zuy. In cases when almost total
Pc attenuation is observed, the traces on the Ushkanly records dis-
appear somewhat later and appear earlier, than in Zuy, but sharply
pronounced Pc within the limits of measurement accuracy are excited
simultaneously. These Pc excitation characteristics are, apparently,
determined by the location of Ushkaniy Island and its
ture. The thickness of the sedimentary sequences in Zuyoexceedstruc?
1000 m, while Ushkaniy Island is composed of metamorphic Precambrian
rocks, The recurrence of certain types of oscillations in the same
hours of several days was detected in the Pc records. Thus, for
example, from 1 Apr through 10 Apr 1952 Intensive Pc, having about
the same regime at the same time of the day,. were observed. These
oscillations were connected with a very stable and geophysically
active region of the sun observed at that time.
A sharp Pc Increase after the commencement of geoelectric
field storms is sometimes observed. This Pc intensity increase is
particularly noticeable when the commencement of the storm occurs
during hours of weak Fe development. Another characteristic of pc
excitation, connected with terrestrial electromagnetic storms and
auroras, is the broadening of the spectrum of short period oscilla-
tions during the phenomena. It is noted that on quiet da
Pc with a period from 10 to se chiefly
3p-~#0 and more seconds are observed,
while during auroras, oscillapione with a period from 1 to 60-70
and more seconds are observed, Of all oscillations of the indicated
spectrum those with a period of about 1-2 sec are particularly
evident; oscillations with a period of about 2 sec occur more often
than oscillations with a period of about 1 sec. An almost complete
constancy of the period for the entire interval is characteristic
of oscillations of both groups.

The equipment used in the Lake Baykal region from 20 Feb
through 1 Apr 1955 to make continuous recordings of the variation
of the potential gradient of the electrotelluric field consisted
of a photogalvanograph and five pick-up lines, three of which. JAY
in-an'eaet-west direction and two in a north-pouth direction. The
electrodes of the eastern lines were submerged to depths of 5,200,
and 1,100 m; those of-the northern line to depths of 5 and 400 ;K.
All electrodes in the same direction were in a single vertical
plane. 0.4 ml lead plates served as electrodes. Each line was
500 m long. 11CM wire was used to link the electrodes to the re-
cording equipment.. The insulation resistance for the lines ex-
ceeded 10 mg ohm/km. Properly shunted self-leveling mirror gal-
vanometers operated in the regime of critical damping., Periodic
measurements of the ground resistance of the electrodes showed a
constant 170 ohm during all observations. Oscillograph recordings

NO types of short period oecillktions, differing from each
other by the nature of their oscillatory reggime, are distinguished.
Type 1, once begun, continue for hours, while Ty 2 are observed
in groups or trains of from 1-10 oscillations. -pe 1 may be
further divided into 3 forms as follows: l) complex harmonic
short period oscillations, the amplitude and period of which change
irregularly; 2) sinusoidal short period oscillations, the amplitude
of which changes irregularly, but which are more stable than Form if
the period remains almost constant for several tens of years; and
3) sinusoidal short period oscillation, the oscillatory process of
which consists of separate packets, containing from 3 to 10 and more
oscillations, the amplitude of which after a smooth increase to
about the center of the packet gradually lessens. Analysis of elec-
trograms shows that most often Form 2 oscillations are excited, and
only very rarely the packet form. The difference in the nature of
the flow of these oscillations is, apparently, connected with modi-
ficatiane in the factors causing them.
The following conclusions are made from the observations:
1) Short period Type 1 and Type 2 oscillations as well as bay-
shaped disturbances of the electrotelluric field at different
depths of Lake Baykal and on land (Zuy) are, within the limits of
measurement accuracy, excited simultaneously, coincide completely
in their parallel march, and have a similar period. Because of the
complete similarity (with the exception of amplitude) of all the
oscillations and impulses, the oscillatory regime of the electro-
telluric field at different depths in Lake Baykal and on land has
the same character. 2) The amplitudes of Type 1 and Type 2 oscil-
lations and of the bay-shaped disturbances in Baykal and Zuy cor-
respond to the electrical resistance of the medium of these points.
3) A slight lessening of amplitude with depth was detected in
Type land 2 oscillations. The value of the attenuation, computed
from the observational materials, is in agreement with the value
of attenuation obtained from examination of the absorbing effect
of Baykal?s waters on the variable electrotelluric field. 4) Local
electric currents, connected with the water currents in Baykal,
were detected. The change in the potential of the field of these
currents represents a series of uneven oscillations with a period
of 2-7 sec and an amplitude of 0.1-0.8 mv/km. 5) Type 1 short
period oscillations in both Zuy and Baykal are excited chiefly in
the interval from 00-1200 hours, while Type 2 occur from 12-2+00
hours, universal time. The greatest recurrence of bay-shaped die-
turbances occurs during nocturnal hours.
