On the question of investigation of variations of the solar constant during the period of the severe geomagnetic storms

Still actinometrical observations in the interplanetary space, scientific workers of the Smithsonian Astrophysical Institute (USA), under his guidance of C. Abbott, obtained conclusion during the period of the severe geomagnetic storms, solar constant, as a rule, is anomalously decreased. This phenomenon is explained by Abbott like this – due to strong solar flare in solar-terrestrial interplanetary space. corpuscular cloud is ejected from the Sun. Corpuscular clouds condition Raleigh scattering of photon emission of the Sun and correspondingly, decrease of solar constant.

Comparison of variations of solar constant and   intensity of the  geomagnetic field in the   period of large and very large magnetic storm (∆Dst £ – 150 nT) demonstrated that all considered cases can be divided into five types, according to the character of solar constant variation. From above stated experimental data  follows undoubtedly that the result of Abbot’s scientific school (“in the day of very large magnetic storm solar constant value, as a rule, is anomalously decreased”) should be corrected so: correlation between variations of solar constant and magnetic storm is not simple.

Comparison of variations of solar constant and plasma cloud concentration of interplanetary medium, with high level of density (PCIMWHLD, n_d ≥ 25 pr.cm ^-3), revealed that   variations  of  solar constant do not at all  react  at changes of PCIMWHLD.  From above-stated experimental data logically follows that there aren’t connection between variations of solar constant and PCIMWHLD. Hence Abbot’s conception that -“due to strong solar flare in solar-terrestrial interplanetary space corpuscular cloud is ejected from the Sun. Corpuscular clouds condition Raleigh scattering of photon emission of the Sun and correspondingly, decrease of solar constant”, unfortunately proved to be incorrect.
