Solar Activity Monitoring

Solar activity and general space weather can be reviewed at the NOAA site: http://www.swpc.noaa.gov/today.html

The site provides solar activity forecasts and geophysical (geomagnetic field) activity forecasts along with GOES X-ray flux values.

Ionosphere Monitoring

Global Ionospheric TEC maps are available via: http://iono.jpl.nasa.gov/latest_rti_global.html
