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:

 

flare-n.gif Normal: Solar X-ray flux is quiet (< 1.00e-6 W/m^2)
flare-a.gif Active: Solar X-ray flux is active (>= 1.00e-6 W/m^2)
flare-m.gif M Class Flare: An M Class flare has occurred (X-ray flux >= 1.00e-5 W/m^2)
flare-x.gif X Class Flare: An X Class flare has occurred (X-ray flux >= 1.00e-4 W/m^2)
flare-y.gif Mega Flare: An unprecedented X-ray event has occurred (X-ray flux >= 1.00e-3 W/m^2) 
The designation "Mega Flare" was chosen by Kevin Loch when the status monitor was created on March 4, 1999. 
There is no "official" designation for flares in this range.

 

 

About the Geomagnetic Field status monitor The 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:

 

geom-q.gif Quiet: the Geomagnetic Field is quiet (Kp < 4)
geom-u.gif Active: the Geomagnetic Field has been unsettled (Kp=4)
geom-s.gif Storm: A Geomagnetic Storm has occurred (Kp>4)

Bonjour

Je connais l'incidence des perturbations du champ magnétique sur le GPS mais qu'en est-il des rayons X ? Perturbent-ils les satellites de la même façon ?

Merci

Bonjour, non je ne pense pas que les rayons X perturbent les satellites pour la simple raison que les rayons X ne sont qu'un simple rayonnement certes dangereux. De plus, si les rayons X perturbaient les satellites, alors il n'y aurait aucun satellite qui fonctionneraient car situés dans l’espace, ils ne sont pas protégés par l'atmosphère contre les rayons X qui ne sont nocifs que pour les êtres vivants.

Et enfin, les rayons X sont utilisés par certains satellites pour faire des images du soleil ou de la Terre.
