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:
(Definition: Kp refers to Kp INDEX. A 3-hourly planetary geomagnetic index of activity generated in Gottingen, Germany, based on the K INDEX from 12 or 13 stations distributed around the world from http://www.sec.noaa.gov/info/glossary.html)
| Quiet | Quiet: the Geomagnetic Field is quiet (Kp < 4)
| | Unsettled | Unsettled: the Geomagnetic Field has been unsettled (Kp=4)
| | STORM! | Storm: A Geomagnetic Storm has occurred (Kp>4)
