Geoalert - Alerts, Analysis and Forecast Codes

Users of the coded GEOALERT report include members of the International Space Environment Service (ISES), a multinational partnership of agencies sharing observed space weather data and collaborating on forecasts. The GEOALERT is a final daily report containing the compilation of observed conditions, as well as a one day forecast.

The GEOALERT message contains four coded messages and sometimes plain text.

UGEOA: The World Warning Agency (WWA) consensus forecast for 1- to 3-day
forecasts of whole-disk flares, geomagnetic activity, and protons.

UGEOE: A summary of significant solar events for the previous day.

UGEOI: Observed solar-geophysical indices for the previous day.

UGEOR: Sunspot data for the previous day, and regional forecasts.

Current day GEOALERT.
