NAME

WMSPACEWEATHER - Dockable Space Weather Monitor

SYNOPSIS

wmSpaceWeather [-h] [-display <Display>] [-noblink]

DESCRIPTION

wmSpaceWeather is a space weather monitor. The monitor shows: 2 relativistic electron and 3 relativistic proton flux levels at geosyncronous orbit (currently from the NOAA GOES spacecraft), current Solar Flare X-ray flux, and the last 8 3-hour Kp index values.

Large fluxes of relativistic (aka `Killer') electrons can cause harmful `deep-dielectric' charging/discharging events inside satellites. High proton fluxes (`Solar Energetic Proton' or SEP events) can cause single event upsets in satellite electronics. The Kp index is a measure of how disturbed the Earth's magnetic field has been over a 3-hour interval. Kp can range from 0-9, where 0 is quiet and 9 is very disturbed. The Kp values shown are the 8 previous values (i.e. the last 24 hours). Have a look at http://www.sec.noaa.gov/wwire.html for further information. If the display is up-to-date, the LED next to the Kp bars will flash blue. If the display is not up-to-date, the LED will flash orange.
