Planetary-K-Index

Track the planetary K-index (Kp) — the standard measure of global geomagnetic activity.

Planetary K-Index shows live Kp from NOAA, official charts from GFZ Helmholtz Centre for Geosciences, and related space-weather products so you can see quiet conditions, active periods, and geomagnetic storms at a glance.

WHAT YOU GET

• Kp — estimated planetary K-index with scrubbable bars, conditions, and a 24-hour forecast

• NOAA — station K & A indices, Boulder magnetometer, geospace, ACE, and aurora maps

• Europe · GFZ — official Kp nowcast charts, Hp30, daily plots, Bartels diagram, plus Poland INTERMAGNET magnetograms (Belsk & Hel)

• Pull to refresh on live data and chart screens

WHY Kp MATTERS

The K-index (and planetary Kp) characterizes disturbances in Earth’s magnetic field. Space weather agencies use it for geomagnetic alerts and warnings. Higher Kp values mean stronger activity — and better chances of aurora at lower latitudes during storms.
