Name and Link Description
STORM - Time Empirical Ionospheric Correction Model provides an estimate of the expected change in the ionosphere during periods of increased geomagnetic activity. The model estimates the departure from normal of the F-region critical frequency (foF2) every hour of the day for the current and previous day.
Solar Image References
Links to current space weather image sites used by the SEC Space Weather Operations staff in performing their daily analysis of current data, climatological statistics, and relevant research results to formulate predictions of solar and geophysical activity.
GOES Satellite Changes

June 17, More GOES Satellite Changes -- SEC's designed primary and secondary GOES satellite have changed again to GOES 12 primary, GOES 10 secondary for all measurements, except energetic protons which have GOES 11 as primary. Details and affects

Solar X-ray Imager (SXI)
NOAA's Solar X-ray Imager (SXI), on the GOES 12 spacecraft, has been returning soft X-ray images of the Sun since January 22 (Press Release). The images are available in near real-time at SEC's SXI site and the National Geophysical Data Center.
SOLAR2000 is an empirical solar irradiance operational and research model developed to accurately characterize solar irradiances across the spectrum. SOLAR2000 produces several solar-related proxies such as E10.7, which can be used in existing solar-terrestrial models where F10.7 is traditionally used. E10.7 offers significant improvement as an index of the energy input to the thermosphere and ionosphere. SOLAR2000 irradiances and E10.7 applications include satellite operations, HF radio propagation, and GPS.
CHEN Model
The Chen IMF Prediction Model is a feature-based pattern recognition technique designed to predict the occurrence, duration, and strength of moderately large to large geomagnetic storms using real-time solar wind data available from a spacecraft upstream from Earth, such as the ACE satellite.
Wang-Sheeley Model
The Wang-Sheeley Model  predicts the background solar wind speed and the interplanetary magnetic field polarity at Earth, two important parameters required for predicting geomagnetic activity (e.g., Ap). Displays include daily predictions of 1- to 7-day advanced solar wind speed and (radial) IMF polarity at Earth and data maps from three solar observatories.

Relativistic Electron Forecast Model
The impact of high-energy (relativistic) electrons on orbiting satellites can cause electric discharges across internal satellite components, which in turn leads to spacecraft upsets and/or complete satellite failures. The Relativistic Electron Forecast Model predicts the occurrence of these electrons in geosynchronous orbit.
