GOES Satellites

High resolution magnetograms from Primary and Seconday GOES satellites

Geomagnetic Field - Bz

Solar wind data from the Deep Space Climate Observatory.

Ionosphere/VLF Monitoring

VLF Monitor - Last 24 Hours

The VLF antenna is a wire loop with approx 50 turns of wire. The signal is passed through a "SuperSID" filter and processed with Spectrum Lab software and custom software. Reception of long distance stations shows a diurnal variation in signal strength. This signal can be altered by space weather and x-rays generated by solar flares.
