【實用天氣app】Sun Activity (kp-index)|最夯免費app-綠色工廠好玩App

The application provides the current value of the Kp-index derived at the NOAA Space Weather Prediction Center using data from ground-based magnetometers. What is Kp-index - The K-index quantifies disturbances in the horizontal component of earth's magnetic field with an integer in the range 0-9 with 1 being calm and 5 or more indicating a geomagnetic storm. It is derived from the maximum fluctuations of horizontal components observed on a magnetometer during a three-hour interval. The official planetary Kp index is derived by calculating a weighted average of K-indices from a network of geomagnetic observatories. Kp of 0 to 4 is below storm, which is G0.Kp-index NOAA Space Weather Scale Geomagnetic Storm LevelKp=5 G1Kp=6 G2Kp=7 G3Kp=8 G4Kp=9 G5
