| Zusammenfassung |
A number of magnetopause
models have been developed in the course of last three decades. We have chosen
seven of them and tested them using a fresh set of magnetopause crossings
observed by Interball-1, Magion-4, and Geotail satellites. The crossings cover
the magnetopause from the subsolar region up to near-Earth tail (XGSE ~ - 20 RE
) and all geomagnetic latitudes. Our study reveals that (1) the difference
between investigated models is smaller than the error of prediction caused by
the factors not included in models, (2) the dayside magnetopause is indented in
the cusp region, (3) the deepness of the indentation can reach ~ 4 RE , and (4)
the dimensions of the indentation do not depend on the dipole tilt, whereas its
location does.
