March 2004 About STATION LISTS These station lists have not been updated since 1995, but are occassionally useful to SEC customers. Please use with caution. Station lists are sorted and grouped in nine different ways: All stations by: Name, Latitude and Longitude All stations by type of data: Optical, Geomagnetic, Ionospheric, TEC, and Radio Flux All satellites Abbreviations are used on some plots and listings. Complete station name and country Station location The station's affliation: URSI - International IUWDS stations USGS - U.S. Geological Survey USAF - U.S. Air Force RGON - International Intermagnet magnetometer stations Type of data sent to SEL: Opt - Optical Observatory reporting solar limb and disk events including solar flares, and region summaries. Mag - Ground-based magnetometer sites, some send A and K indices, others send H, D, and Z components, and some send both. Iono - Ionospheric stations sending hourly values of foF2, M3000, fmin, and/or foes. Radio - Solar Radio Flux at various frequencies. Some also report radio bursts. TEC - Total Electron Content. Fsct - Stations that routinely forecast solar and geomagnetic activity. Sat - Satellites. GOES satellites are tracked by SEL in real-time but the NOAA satellite data is received only every ??hours.
