The N3KL web site provides
a solar activity monitor, as viewed above, that indicates the current solar
status of the solar X-rays and the geomagnetic field. The status is determined
from the analysis of data periodically downloaded from the FTP server of the
NOAA Space Environment Center.
Below is presented the meaning of each status level in the monitor.
Solar Activity Status
The previous 24 hours of 5 minute long-wavelenght X-ray data
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)
(<=1,00x10-6 W/m2 )
|
|
|
ACTIVE:
Solar X-ray flux is active (>= 1.00e-6 W/m^2)
(>=1,00x10-6 W/m2 )
|
|
|
M CLASS FLARE:
An M Class flare has occurred (X-ray flux >= 1.00e-5 W/m^2 )
(>=1,00x10-5 W/m2 )
|
|
|
X CLASS FLARE:
An X Class flare has occurred (X-ray flux >= 1.00e-4 W/m^2)
(>=1,00x10-4 W/m2 )
|
|
|
MEGA FLARE:
An unprecedented X-ray event has occurred (X-ray flux >= 1.00e-3 W/m^2)
(>=1,00x10-3 W/m2 )
|
Geomagnetic field status
The previous 24 hours of 3 hour 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)
(kp < 4)
|
|
|
UNSETTLED:
the Geomagnetic Field has been unsettled (Kp=4)
(kp = 4)
|
|
|
STORM:
A Geomagnetic Storm has occurred (Kp>4)
(kp > 4)
|
