The geomagnetic station in Tamsweg is a part of a regional station network, which was and is being set up in close cooperation with three high schools as part of a Sparkling Science project (Sparkling Geomagnetic Field). This station (called "Tamsweg-Sedna", from which the acronym "TSE" derives) with two sensors - one fluxgate variometer and one Overhauser magnetometer - was installed in a school in Tamsweg, Styria, and has been running permanently since then. The variations that you see here are caused mainly by the magnetically noisy schoolday. In this plot 7 days of magnetic variations are shown. The part highlighted in green shows the comparatively quiet weekend.
