AbstractAbstract
[en] The inferred polarity (towards or away from the sun) of the interplanetary magnetic field at earth using polar observations of the geomagnetic field has been compared with spacecraft observations. A list published by Svalgaard of the inferred field polarities during 1970 through 1972 is found to be correct on 84 percent of the days. A near real time (same day) method of inferring the polarity of the interplanetary magnetic field using geomagnetic observations at Vostok and Thule is in use at the NOAA Space Environment Laboratory, Boulder, Colorado. During 1972 this method is found to be correct on 89 percent of the days. A list of well-defined sector boundaries at earth during 1970 through 1972 is given. (auth)

AbstractAbstract
[en] Widths of the equatorial boundary of convection electric field depending on local geomagnetic time are detrmined using data obtained due to the network of the USSR, high-latitude ionosphere stations. Comparison with model estimations is conducted. Conclusion is made, that divergence of experimental and model values results from the effect of JMT on position of this boundary

AbstractAbstract
[en] It is shown that the strange attractor in phase space of the Rikitake two-disc dynamo is supressed by weak, if any, external magnetic field. Reversals of the external field causes the reversals of the dynamo field. Extension of the result obtained to geomagnetic dynamo taking into account inhomogeneous galactic magnetic field provides an explanation of the time scale for geomagnetic reversals

AbstractAbstract
[en] Preliminary results of an analysis of nucleonic intensity data from polar and equatorial stations has revealed a definitive relationship with two plasma parameters, IMF (B) and solar wind speed (V). For large values of B, the nucleonic intensity decreases by more than 1.5%. In contrast, the nucleonic intensity increases significantly (>0.3%) for B<5γ

AbstractAbstract
[en] The solution of the field equations in the interplanetary medium has been obtained in the assumption that the Sun's magnetic field is nonstationary and inhomogeneous in latitude and longitude. In addition to the Parker spiral magnetic field, this solution contains the latitude component of the magnetic field. The corresponding change of the magnetic and electric particle drift velocities and the energy variations of particles dE/dt are calculated. The conditions under which dE/dt>0, i.e. when the particle acceleration start being accelerated are found

AbstractAbstract
[en] The mean solar magnetic field as measured in integrated light has been observed since 1968. Since 1970 it has been observed both at Hale Observatories and at the Crimean Astrophysical Observatory. The observing procedures at both observatories and their implications for mean field measurements are discussed. A comparison of the two sets of daily observations shows that similar results are obtained at both observatories. A comparison of the mean field with the interplanetary magnetic polarity shows that the IMF sector structure has the same pattern as the mean field polarity. (Auth.)
