Report of Solar and Geophysical Activity - The Report and Forecast of Solar and Geophysical Activity is the primary daily report prepared by SEC. It provides a summary and analysis of solar and geomagnetic activity during the previous 24 hours as well as the most recent solar indices. It also provides a forecast of activity and indices for the next 3 days.

NOAA Space Weather Scales - The NOAA Space Weather Scales were introduced as a way to communicate to the general public the current and future space weather conditions and their possible effects on people and systems. The scales describe the environmental disturbances for three event types: geomagnetic storms, solar radiation storms, and radio blackouts.

ATPDEC - Atpdec is an open source program that decodes images transmitted by POES NOAA weather satellite series. These satellites transmit continuously, among other things, medium resolution images of the earth on 137Mhz. These transmissions could be easily received with an inexpensive antenna and dedicated receiver. For more information about receiving POES satellite images consult the rig site.
