About the Solar X-ray status monitorThe X-ray Solar status monitor downloads data periodically from the NOAA Space Environment Center FTP server. The previous 24 hours of 5 minute Long-wavelength X-ray data from each satellite (GOES 8 and GOES 10) is analyzed, and an appropriate level of activity for the past 24 hours is assigned as follows:

Normal: Solar X-ray flux is quiet (< 1.00e-6 W/m^2)

Active: Solar X-ray flux is active (>= 1.00e-6 W/m^2)

M Class Flare: An M Class flare has occurred (X-ray flux >= 1.00e-5 W/m^2)

X Class Flare: An X Class flare has occurred (X-ray flux >= 1.00e-4 W/m^2)

Mega Flare: An unprecedented X-ray event has occurred (X-ray flux >= 1.00e-3 W/m^2)

About the Geomagnetic Field status monitorThe Geomagnetic Field status monitor downloads data periodically from the NOAA Space Environment Center FTP server. The previous 24 hours of 3 hour Planetary Kp Index data is analyzed and an appropriate level of activity for the past 24 hours is assigned as follows:

Quiet: the Geomagnetic Field is quiet (Kp < 4)

Active: the Geomagnetic Field has been unsettled (Kp=4)

Storm: A Geomagnetic Storm has occurred (Kp>4)
