From
n3kl.org The 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)
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) |
