The National Weather Service (NWS) provides Direct Broadcast Systems that distribute emergency weather conditions and forecasts to North America and parts of Central and South America. In 1996, the Space Environment Center (SEC) began distributing Space Weather products on NWS direct broadcast systems. SEC currently issues 24 space weather alerts and 12 space weather products on these systems. These products are also available from SEC via Internet connections and e-mail.
The table below links to the web products. Links that start with the /ftpdir/ path can be accessed via Anonymous FTP: ftp.sec.noaa.gov, or ftp2.sec.noaa.gov. Use the web URL shown below (/ftpdir/latest/curind.txt) and replace the path ("/ftpdir/latest/") with an FTP change directory command ("cd pub/latest/") and get the filename ("get curind.txt").
