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. |

Operations staff in performing their daily analysis of current data, climatological
statistics, and relevant research results to formulate predictions of solar
and geophysical activity. |

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

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. |

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. |
| |
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. |

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. |
