September 2011 G2 Geomagnetic Storm
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 magnet
ometer) 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.

Sunday, September 25, 2011 - G2 Geomagnetic Storm
Overnight: PDF, TXT. There is some activity mid-morning PDF. Now a G2 geomagnetic storm by NOAA Space Weather PDF, so far just before 2 pm local NY time EST (~1800 UTC), although certainly storm-like in nature, the swings in the total field (F scalar) have not been that large (<100 nT) here in upstate, NY PDF. 2:40 pm PDF, NRCan Ottawa PDF. 4:18 pm, now on a 200 nT vertical scale PDF. 8:00 pm PDF, NRCan PDF.
Tuesday, September 27, 2011
Overnight: PDF, TXT. Summary view of yesterday's geomagnetic storm PDF.
Carl Olsen's view of the G2 magnetic storm in Colorado Springs, CO PDF, TXT, several day view showing several quiet day geomagnetic diurnal cycles before the storm PDF.
