ABSTRACT: Analysis of the distribution of magnetic perturbations
observed at high-latitude observatories and stations
in the Central Arctic led Nikollskiy (Refs 1-3) to
suggest the existence of a second zone of high magnetic
activity and aurorae. Such a zone ruld occur at
geomagnetie latitudes of about 78-80 . Independently
of,Nikollskiy, Alfven (Ref 4) concluded from his
studies of the motion of ionised particles from the Sun
in the magnetic Peld of the Earth, that there should
exist at q)-.,80 a second aurorae zone. This zone
should be considergbly weaker than the main auroral
zone at i$ - 65-66 denotes here the geomagnetic
latitude). Fig.1 gives the distribution of the'aurorae,
as a function of the geomagnetic latitude, observed in

TEXT: On the basis of magnetograms of;observatories Dikson and Chelyuskin
obtained in the period from July.1956'to July 1957, the;indices of the magnetic

courses.of the magnetic activity were calculated.. The comparison of the results
obtained with the aid of'the Q-indices with the analogous results based on other
indices of magnetic activity (hourly amplitudes of the horizontal component, K-
index) made it possible-to compare the potentialities of the q-index and,other.

TITLE: The geographical distribution of auroras polaris and the azimuths
of arcs

sb. "Issled. polyarn. siyaniy, no. 4", Moscow, AN SSSR, 196o, 61-
78, English summary)
TEXT: The probable appearance of auroras polaris over a given point was
evaluated from the ratio of the humber of nights with zenith aurora to the total
number of nights when observations were made. Continuous photographic observa-
tions at 39 stations (24 Soviet and 15 forelgh stations) and hourly visual ob-
servations of the auroras at three Canadian stations during the winter 1957/1958,
served as initial material for the jorthern hemisphere. To determine the loca-
tion of the zone of auroras polaris and the location of the station in respect
to the zone, the number of auroras to the North and the South of the station was
compared. The observations have shown that the location of the zone of auroras
polaris during magnetically-quiet and magnetically-disturbed days was somewhat
Card 1/ 3

different. The distance between them was on the average 30-50 in latitude; dur-
ing magnetically-disturbed days the zone was situated more to the south than
during magnetically-quiet days. Depending on the latitude some changes were ob-
served in the recurrence of auroras Polaris. There is a sharply marked maximum
of intensity in the zones of aurora polaris and a monotonous north-and southward
decrease in the latitudinal distribution on magnetically disturbed days. During
magnetically;quiet days a distinct maximum of auroras polaris recurrence in the
zenith appea s 80-100 to the north from the zone of auroras Polaris. The prob-
able appearance of auroras Polaris at the zenith at these stations which are loc-
ated far inside the zone of auroras polaris, can be compared with the probable
appearance of the auroras inside the zone of auroras polaris. Apparently, this
is a second zone, but itis observed only during magnetically quiet days. It was
also established that far inside the zone of auroras Polaris, the auroras appear-
ed much more frequently during magnetically quiet than magnetically disturbed
days. In the very zone, the reverse phenomenon was observed towards the south
and somewhat to the north. The comparison of zones of aurora Polaris in the Arc-
tic and Antarctic indicates their somewhat different form and a considerable dif-
ference in their diameters. In the Antarctic, the zone of auroras polaris is
almost a circle with about 200 radius; in the Arctic it is a prolate oval with

its center in the homogeneous magnetization pole, and 200 minimum and 280 maximum
radius. Such a difference in the radius and shape of the zones of aurora polaris
can in the first approximation be explained by the difference between the con-
stant magnetic field of the Earth and the dipble field. Diurnal changes in the
recurrence of auroras polaris in the zenith Indicate that there are two maxima
of recurrence, namely the "early" and "nocturnal" one. The oval shape of the
zone of aurora polaris can.be explained by the deformation of the magnetic field
of the Earth due to the incoming corpuscle flows. Theoretical calculations yield
a spiral shape of particle settling, even If the magnetic field is not different
from the dipole field, i.e. if there is no deformation of the magnetic field at
great distances fromt he Earth. Observations of the azimuths of aurora polaris
arcs show that rotation of the latter takes place; this can be explained by the
fact that the zone of polar auroras has an oval shape; the evening (nocturnal)
spiral has greater azimuths than the early spiral. There are 28 references.

TITLE: Magnetic Variations Within the Main Zone of Aurora
PERIODICAL: V sb.: "Probl. Arktiki i antarktiki". No. 3, Leningrad, "Morsk.

TEXT: To study the variability of the components of the magnetic field
within the auroral zone, a temporary record of the magnetic field was carried out
from April 6 to May 6, 1957, in the Nagurskaya Bay (Franz Josef Land) which Is
10*cated 108 km from theTIkhaya Bay. Prom the comparison of the magnetograms
obtained in the Tikhaya Bay and Nagurskaya. Bay, I. e., characteristical extrema,
in the H- and Z-components, a functional correlation was detected between the
variations at both points, especially clear for the vertical component. The
nature of the changeability of magnetic field variations north of -the auroral
zone differs considerably from the variations within the zone. Z noticeably
changes within the auroral zone at distances of about 100 km, whereas within the
auroral zone the variability considerably decreases. The explanation of these

stations within the zone may be less than that within (?) the zone of aurora
when the network of temporary stations is established.

of the statistical processing of the hourly amplitudes of the horizontal component
and the deflections of the absolute value of the field in a given hourly interval
from the corresponding value in a~stable day for the same month according to data
from the polar observatories in the period 1935 - 1936; the obtained distribution
curves are interpreted. It Is concluded that the distribution curves of the

absolute values consist of two parts: 1) the Gauss distribution for small
absolute values of the variation field; 2) the deflection from the normal
distribution curve at great values of the field. The author considers the
connection of the hourly amplitudes with the absolute values H for various periods
of 24 hours, and the connection of the diurnal course of the modulus of the
absolute values of the perturbation vector of the magretio field. Qualitative
results are presented. There are 14 references.

TEXT:. The authors investigate seasonal variations in the frequency with
which polar aurorae appear and exclude the effect of differences in duration
of observation by taking data for a definite period of time each day from a
number of stations located in the aurora and polar regions of both hemi-
3pheres. The results confirm the conclusions of other authors that
equinoctial maxima in the frequency with which aurorae appear occur in the
aurorae zone and also show that there is no maximum in winter months in the
polar region, There are 3 figures, 1 table and 7 references: 4 Soviet and

Polar aurorae and the anomalous absorption of typ~~-III
radio waves
Geomagnetizm i aeronomiya, v. 1, no. 6, 1961, 939-941
TEXT: Polar aurorae with absorption of type-III radio waves (absorption in
the polar cap) and geomagnetic storms are discussed on the basis of obser-
vations made in the South Pole region. Most of the data usedare of Western
origin, and on this basis the author finds that the entry into the Earthts
atmosphere of solar protons, which cause anomalous absorption of type II,
has no connection with polar aurorae; that these coincide at the geomag-
netic pole with the beginning of a geomagnetic storm and disappear quickly
as the storm proceeds. The corpuecular flows,which cause aurorae in the
polar region (as distinct from the auroral region),reach the high latitudes
at the beeinning of a storm along the force lines of a magnetic dipole.
Later the geomagnetic. field is so deformed by the flows that the entry of

TEXT: The space-time distribution of the aurorae observed at the Soviet antarctic station Lazarev in
February-October 1960 shows that the southern auroral zone does not extend over the southern geographic
pole; this zone is rather a - 25* circle circumscribing the southern magnetic pole and getting no closer
than 1000 km to the southern geographic pole (Ref. 2: F. R. Bond, F. Jacka. Austral. J. Phys., 1960,13.610).
The asymmetry between thenorthern and the southern ouroral zones can be explained by deviations or the
actual gcomagnetic field from the field or a dipole. There are 2 figures and I table.

TEXT: Hourly values of the magnetic activity 9-index are

polyus-7" Worth Pole 7), Resolute Bay, and College for the winter
months of 1957/1958 and 1958/1959. In the auroral zone (College)
the presence of a zenith aurora is, as a rule,-related to a marked
degree of magnetic disturbance. Zenith auroras are absent if the
magnetic field is comparatively quiet. On the inner side of the aur-
oral zone the relation is inverse: zenith auroras are on the average

associated with a quieter magnetic field; in the absence of an auro-
ra the field is more disturbed. On these grounds it is concluded
that i-a the circumpolar region glow-inducing particles have insuff'
cient energy to penetrate to the 1-d-layer, where currents responsible
for polar magnetic disturbances flow. It is supposed that solar
particles hitting the auroral zone first accelerate in the earth's
radiation belt, while particles entering circumpolar regions fly
directly from, the sun and undergo no further acceleration. From
these deliberations it'is concluded that in the circumpolar region
the auroral altitude must be higher than in the auroral zone. Com-
parison of some spectral auroral characteristics, observed on the
inner Bide of the zone and in the zone itself, confirm this conclu-
sion. Strong magnetic disturbances with no zenith appearance of
auroras are sometimes noted in the circumpolar region. In such
cases a still stronger degree of disturbance was observed in the
auroral zone, i.e. the degree of disturbance on the inner side of
the zone was just an echo of disturbances in the zone. Uuring ex-
ceptionally strong magnetic disturbances (for example, on February
119 1958) zenith auroras also appear on the innerside of the zone,

i.e. corpuscular flows then penetrated to the D- and E-layer level
throughout the polar cap (penetration of particles.to the D-layer
can be Judgedby complete absorption at ionospheric stations). In
the auroral zone the zenith appearance of an aurora is, as a rule,
accompanied by the formation of the Es-layer. On the inner side of
the zone this is not observed, which confirms the conclusion that
particles penetrate leas deeply into the circumpolar region.

ABSTRACT: The auroral zone, according to statistical Investigations
during the IGY, has an oval shape with the minimum distance from the
geomagnetic pole on the daylight side and the maximum distance on the
night side. The same applies to auroras. The polar distance of the
zone on the night side stretches to the 67th geomagnetic parallel and
to the 77th parallel on the daylight side. The polar distance of the
auroral zone changes, depending upon the magnetic activity. In - '
Periods with magnetically quiet days, the auroral zone contracts near-

er to the magnetic pole. A comparison of activity recorded by two
drift stations Arctic Ice Flow and the Soviet Arktika-2 shows a dis-
agreement in results. The station Arktilca-2 recorded many auroras
in the day, but midnight records were scarce. The station Arctic Ice
Flow recorded auroras in daylight as well as at midnight, In magnet-
ically quiet periods, the asymmetry of the magnetosphere can be stud-
ied. The oval zone is located on theouter border of a region in
which electrons of energies more than 40 kev are captured. A shift
of the oval zone indicates that the force lines of the geomagnetic
field are farther from the earth in the equatorial plane. The, ob-
served posit of the oval zone on the night side of the earth makes
it possible to determine the maximum distance of geomagnetic force
lines from the earth on magnetically quiet days. Orig. art. has: 1

ABSTRACT: 71ic physical theory of the so-called auroral radar echoes from the Ionosphere
of high latitudes in the 30-1000 Me range includes two basic' processes. The first concerns the
mechanism of reflection or scattering by means of which It Is possible to explain the occurreaci
of echo signals at these frequencies proceeding from the permissible values of the electron
density in the regions of auroral Ionization. The second question Is associated with Interpret-
ing'the characteristic space and time peculiarities inherent to this type of reflection. The pros
ent article is devoted to the second problem based on radar Investigations of ionization in the
polar aurora regions in the Northern Hemisphere, The 19 stations Involved in the Investiption

ACC NRI AT6026925
were divided into two groups, in each of which the statistical characteristics of the observed
radar,echoes were substantially different. The statistical data revealed that reflections from
regions close to the auroral zones occur with greatest probability during those h(mirs of the day
when, according to the theory of the polar current vortex, the current density Is maximal. A
later pealt of reflections recorded at most middle-latitude stations between 2400 and 0400 local
time is accompanied In all cases, without exception, by a decrease of the horizontal component
of the magnetic field. The first peak occurring between 1700 and 2100 hr is characterized by -,*-
the development of a different type of magnetic activity. It can be established that for stations
of the Jodrell Bank typo, near where the constant field is not disturbed by the presence of
anomalies, this activity is associated with an Increase of the horizontal component. It Is con-
cluded that reflection from'the zone of polar auroras Is an effect which owes its pattern of be-
havior to the development of the polar current vortex of a magnetic storm. The frequency of
the appearance of radar echoes depends on the conditions of the occurrence, disappearance,
and shift during the day of regions of high anomalous Ionization. Therefore, the presence of a
close relationship between magnetic disturbances and the appearance of radar echoes should be
expected, and actually the time regularities of magnetic activity and auroral reflections occur
Identically In basic features. The periods of maximal values of the frequency of appearance of
radar echoes vary in relation to the geomagnetio, latitude of the station. A comparison of the
spiral distributions of magnetio activity with the corresponding dilAributions of the auroral
ultrashort-wavo reflections revealed that they practically coincided in the entire range of in-

ATG02692.ry
stfpted latitudes, Wo indicated that the penetration of corpusoular fluxes Into the upper
layerg of the atmosphere has a direct and simultaneous effect both on the oocurrewe of goo-
mapsUo activity and on the appearance of radar ultrashort-wave reflections. Ori& art. luws

ABSTRACT: The frequIecy of occurrence and other properties of auroras
during the minimum solar activity are investigated using photographs
obtained during the IGYQS, The latitudinal distribution of the fre-
quency of occurrence of auroras during the period from 1963 to 1965 is
presented graphically for the winter months.. Observation data obtained
at Dixon and Chelyuskin stations shows that auroras occurring at mid-
night are observed in the northern sky and south of the zenith,
respectively. The oval auroral zone observed at night was located
between 690 and 700 northern geomagnetic latitude. Auroras were observd

within the oval auroral zone regardless of the decrease of solar
activity. The central line of the zone at night observed duri.ng the
solar actit.,ity minimum was shifted toward the.pole. At night, the oval
zone was located between 68" and 71* geomagnetic latitude. The diurnal
variation in the frequency of.occurrence of auroras has one maximum at
midnight at geomagnetic latitudes less than 68* and two maxima at mid-
night at 710 latitude. The observed maxima were attributed to the
asymmetry of the auroral zone, which is nearer to the pole during the
morning and evening than at midnight. The change of the position of
the oval auroral zone in the IGY and the IGYQS was the same. Azimuths
of,stretched auro7rao changed markedly during the IGY as well as in the
diurnal and yearly periodo# Orig. art, has: 3 figures.

PERIODICAL: Vestnik avyazi, 1959, Nr 1, pp 23 - 24 (USSR)
ABSTRAM To detect the location of sheath faults in communication
cables, marker gases of radioactive and non-radioactive type
may be used. Recently Soviet cable repair crows abandoned
the use of radioactive marker gases because of various short-
comings, and turned to the use of halogenated hydrocarbons
under the trade names of freon 12 and freon 22 the proper-
ties of which are indicated in table 1. Their advantages
for the given purpose are expounded. They are used in con-
nection with the GTI-2 leak detector (Figure 1) consisting
of two parts, the pickup and ventilation device and the
Card 1/2 measuring block. The use of freon for cable-sheath fault
