Build a Geomagnetic Observatory ! GELLER Labs "Backyard Science"
Thoughts on a proton precession magnetometer design - a Proton Magnetometer Project. Build an Earth's field magnetometer.
The FDM MAGNETOMETER1 project is a low cost high performance proton magnetometer (a digital magnetometer) kit under development for universities and amateur scientists to be able to accurately measure and monitor changes in the Earth's total magnetic F field and to observe geomagnetic storms. Magnetic storms can cause large excursions in the field and are of concern to interests ranging from electrical power grids, radio communications, and satellite operations, to aurora watchers and amateur radio operators.
1 Filter Diagonalization Method "FDM" (harmonic inversion), see Jan 21 and Jan 23 entries, based on: Vladimir A. Mandelshtam, Howard S. Taylor, Harmonic inversion of time signals and its applications, Journal of Chemical Physics (1997), Volume 107, Issue 17, 1997, Pages 6756-6769

Overnight: PDF, TXT. The geomagnetic field was very quiet overnight. The downturn at the end of this magnetogram shows the beginning of our normal quiet day diurnal cycle.

Overnight: PDF, a number of cars parked within a couple of hundred feet of the counter-coil sensor pair, this is the relatively undisturbed part of our overnight record, one of the perils of a suburban amateur geomagnetic observatory.

Overnight: PDF, TXT, nice view of today's diurnal cycle PDF.

Overnight: PDF, TXT, magnetogram showing the last four days PDF of the local geomagnetic field (total field "F" scalar) diurnal cycle. Our nominal local geomagnetic field has now fallen below 53,660 nT.
