| Zusammenfassung |
| Adopting an appropriate procedure suitable
for processing the amplitude-time records based on the two-component spectral
analysis technique, the statistical information on Ps6 and other longer periods
are worked out on the geomagnetic field registrations in the Indian longitudinal
regions at and away from the equatorial electrojet influence. The storm interval
during 21 and 22 September 1982 has been chosen for the analysis, as violent and
regular cyclic variations of the geomagnetic field were recorded in all the
three components of the field at the Indian observatories. The procedure, when
applied to two intervals of afternoon and night conditions of equatorial
ionosphere, showed practically the same polarisation characteristics in the H-D
plane at all the frequencies under the equatorial electrojet. At far away places
from this influence, the ellipticities are found to be relatively to the west
during the afternoon. These, along with the other results, are discussed. |
