3 days ago · The planetary 3-hour-range index Kp is the mean standardized K-index from 13 geomagnetic observatories between 44 degrees and 60 degrees northern or southern geomagnetic latitude. The label 'K' comes from the German word 'Kennziffer' meaning 'characteristic digit.'

Mar 28, 2025 · The Kp-index is a global auroral activity indicator on a scale from 0 to 9. You can use it as a guide to estimate how active the aurora is and at what latitude aurora might be visible.

The Estimated 3-hour Planetary Kp-index is a preliminary Kp-index derived at the NOAA Space Weather Prediction Center using minute by minute data from a number of ground-based magnetometers that relay data in near-real time.

The planetary Kp-index is a globally averaged indicator of the worldwide level of geomagnetic activity. The official Kp index is derived by calculating a weighted average of K-indices from a predetermined network of geomagnetic observatories, the official Kp network.

Kp and Kpa — planetary 3-hourly indices of geomagnetic activity. Data from GFZ Potsdam (Kp-index from 1932-present) and NOAA NCEI (AA-index converted to Kpa from 1868-1931) Sunspot numbers from WDC-SILSO, Royal Observatory of Belgium, Brussels. A plot of the current Kp-index is located here: http://www.theusner.eu/terra/aurora/kp.php

The planetary 3-hour-range index Kp is the mean standardized K-index from 13 geomagnetic observatories between 44 degrees and 60 degrees northern or southern geomagnetic latitude. The scale is O to 9 expressed in thirds of a unit, e.g. 5- is 4 2/3, 5 is 5 and 5+ is 5 1/3.

Kp goes back to 1932 and is an important parameter to investigate long-term climate change in the upper atmosphere, in geospace, in the solar wind and on the sun. Kp is based on the data of 13 geomagnetic observatories around the globe.
