The Magnetometer

The plot below is a template. Click on the plot to get current data.

The magnetogram updates each full 10 minutes. You must actively refresh your browser to see the most recent magnetogram. My website is not updating your browser automatically. You will typically see the 24 h magnetogram but sometimes the 1 h magnetogram, depending on which plot is active here locally.


The SAM III Magnetometer comprises 3 Fluxgate sensors in order to measure the North-South component (Bx, blue), the East-West component (By, red) and the vertical component (Bz, green) of the local Earth magnetic field.

The device is still located inhouse and the rapid signal shifts are mostly due to mechanical disturbancies. I am planning to find a more quiet location  in future
