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
