Group: Summary
X-ray data are collected by sensors on the SMS/GOES geostationary satellites
(6.6RE) over the Earth's equator. Usually there are two satellites recording
similar data at all possible times. One is the 'Western' satellite nominally
located at 135 degrees west longitude. The other is the 'Eastern' satellite at
around 75 degrees west longitude.
Solar X-ray flux levels, as measured on board the satellite by the space
environment monitor system (SEMS), are at two wavelength bands XL: 1-8A and XS:
0.5-4A 'long and short' wavelengths, respectively. They are recorded in units
of watts per square meter. These wavelengths provide extremely sensitive full
disk measurements and are critical for detection of solar flares. They also
are used directly for computing D-region sudden ionospheric disturbances (SID)
and short-wave fadeouts (SWF). Counts are made every 3.6 seconds.
