K-Index Definition
|
||||||
| The K-index is a code that is related to the maximum fluctuations of horizontal components observed on a magnetometer relative to a quiet day, during a three-hour interval. The conversion table from maximum fluctuation (nT) to K-index, varies from observatory to observatory in such a way that the historical rate of occurrence of certain levels of K are about the same at all observatories. In practice this means that observatories at higher geomagnetic latitude require higher levels of fluctuation for a given K-index | ||||||

| The graphics represent solar cycles 21-23. The red line
is the monthly smoothed sunspot number while the blue line is the actual
monthly sunspot number. Cycle 21 started in June 1976 with a smoothed sunspot
number of 12.2. Cycle 22 started in September 1986 at 12.3. Cycle 23 started
in May 1996 with the monthly SSN at 8.0 and peaked in April 2000 at 120.8.
The last smoothed monthly sunspot number is for March 2007 at 10.8.
The current solar minimum will likely be in August-November 2007 with cycle 24 peaking in 2011 or 2012 |
