| Zusammenfassung |
| The presence of polar patches as observed
simultaneously in the same magnetic meridian of opposite nightside ionospheres
by coherent and incoherent scatter radars are described. The patches appear to
be related to variations either in the Bz or By
component of the interplanetary magnetic field which cause transient merging on
the dayside magnetopause. The passage and characteristics of polar patches as
they traverse the polar cap into the nightside auroral oval are not
significantly affected by the occurrence of small substroms. This study
illustrates how the observations of polar patches in the nightside high-latitude
ionosphere could be of great value in determining their formation process. |
