SOVIETS BUILD NEW ASTRONOMICAL OBSERVATORIES
A Siberian scientific station for observations of the solar corona is being
organized in a mountainous region southwest of Irkutsk. The observatory being
constructed near Tartu has been assigned the role of central astronomical
institution for the Baltic republics.

TEXT :
Astronomical determinations of clock corrections are performed with
two transit instruments (4 observers). The chain method of observations is
employed to detect errors in direct ascensions of the FK3 catalogue (R) "of the
form Aad. Time keeping is conducted by means of a pendulum clock (root-mean-
square variation of diurnal run was confined within 2 msec) and a KM-1 (KI-1)
quartz clock (variations of diurnal run are of the order of +0.4 to -0:5 msec) .
A synchroscope with a phasing motor is employed for reception of second signals.
Errors in recording signals became less than 0.1 msec. 19 deliveries of second
signals are controlled, as well as 3 transmissions of rhythmical signals and 10
transmissions of the new type signals ( from stations of frequency standard) and

TITLE :
Beat-type oscillations in the electromagnetic field
of the earth (according to observations in Irkutsk)
PERIODICAL: Geologiya i geofizika, no.11, 1962, 114-124
TEXT :
Regular observations of. PP-oscillations were begun at
Irkutsk in August 1957. The present paper reports results obtained
as a result of four years of observations.
The PP-oscillations
have the form of beats. The most frequently encountered
repetition frequency of these beats was found to be 0.3 to 0.1 cps.
The most frequently encountered frequency of the "carrier" was
found to correspond to a period of 0.6 to 1.0 sec. Finally, the
maximum amplitude of the resultant oscillation was found to lie
between 0.05 and 2.5 mV/km, but the most frequently encountered
values were in the range 0.15 to 0.60 mV/km. A study was also
made of the diurnal variations in the frequency of appearance of
the PP-oscillations, the diurnal variation in their intensity and
the seasonal distribution.
A further study was concerned with
changes in the ionosphere during PP-oscillations and their
geographical distribution.
A survey of the results obtained at

twelve different stations shows that for geomagnetic latitudes
greater than 40' the mean monthly repetition frequency of
PP-oscillations is given by the empirical formula n = - 3.8 + 0.15 9
where y is the geomagnetic latitude."
It is noted that the
results now reported are only preliminary.
There are 6 figures
and 15 tables.
