Ips-esws-general -- Severe Space Weather Warning
About Ips-esws-general	English (USA)
Under severe space weather conditions there is an increased risk of impacts to critical infrastructure such as power networks, GPS navigation and timing systems, HF radio communications, and satellite systems. "Severe space weather WATCH" messages are issued when an event has occurred on the sun with characteristics typical of previous events that have resulted in severe space weather. The assessment of severity of a given solar disturbance is based on the interpretation of the Duty Forecast Officer, being informed by both remote observation of the Sun and statistical modelling of the event (for more details of the statistical model please contact ASWFC@bom.gov.au). These messages should therefore be considered as advisory notifications for possible severe space weather conditions. "Severe space weather EVENT IN PROGRESS" notices will follow should a severe space weather storm eventuate. "Severe space weather EVENT END" will follow when activity subsides and/or "Severe space weather CANCELLATION" messages will be issued when the threat period has expired. More specialised warning and alert products for specific industry groups are being developed. If you would like further information or tailored products please contact ASWFC@bom.gov.au To follow the event in more detail please go to www.sws.bom.gov.au To see the collection of prior postings to the list, visit the Ips-esws-general Archives.
