The Space Environment Center (SEC) is the Nation's official source of space weather alerts and warnings for disturbances that can affect people and equipment working in the space environment. SEC implemented the Space Weather Advisory service to provide "plain language" advise for our customers and keep them abreast of current and expected space weather information .

Space Weather Advisories

Space Weather Outlooks

Space Weather Bulletins Issued when conditions occur that are thought to be of interest to the public.
Space Weather Alerts and Warnings Space Weather Alerts and Warnings are issued when a significant space weather event; is imminent, is likely, has been observed, is in progress, or has ended. NOAA Scale keywords are included on Alert and Warning messages where appropriate.
