- Planetary K-index - NOAA NWS Space Weather Prediction Center
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 '
- The Kp-index | SpaceWeatherLive. com
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
- KP Index Explained – See The Aurora
The Kp-index is a scale used to characterize the magnitude of geomagnetic disturbances A geomagnetic storm starts at Kp5 after which the G-scale is also used Magnetometers measure the strength of Earth’s magnetic field to determine the K-index, which is tied to a specific station
- Kp Index - Kp index - gfz-potsdam. de
The geomagnetic three-hourly Kp index was introduced by Julius Bartels in 1949 to measure solar particle radiation by its magnetic effects (see Bartels, 1957) Today Kp is an important measure for the energy input from the solar wind to Earth and it is used by space weather services in near real-time
- Kp index and the aurora: explained from Kp0 to Kp9
The general rule is that as the Kp index rises, the aurora extends further from the polar regions toward the equator and becomes more active, bright, and colorful Let's see what each Kp level means for the aurora
- SWS - Latest Conditions - Geomagnetic Indices
The K index is a measure of geomagnetic activity for a 3-hour period The larger the K-index, the greater the chance of seeing an aurora at lower latitudes The auroral oval prediction tool shows the predicted visibility line for a given K-index and time of day

When and where can you see the northern and southern lights also known as the aurora? This page provides a prediction of the aurora’s visibility tonight and tomorrow night in the charts below The animations further down show what the aurora’s been up to over the last 24 hours and estimates what the next 30 minutes will be like
