<p><strong>Abstract.</strong> Different magnetopause models with a diverse level of complexity are in use. One thing that they have in common is that they are mainly based on near-earth observations; i.e. they use measurements at distances of about <span class="inline-formula">±10</span> Earth radii along the GSM <span class="inline-formula"><i>x</i></span> axis. Only very few observations of magnetopause crossings at larger distances are used for model fitting. In this study we compare

We find differences in the location prediction between model and actual observation but good agreement in predictions about the magnetopause normal direction.</p>
