Major update: clearer planetary Kp (K-index), NOAA & GFZ charts, Europe views, and pull-to-refresh — from the makers of Quick Schumann Check.
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.
FROM THE MAKERS OF QUICK SCHUMANN CHECK
A focused companion for people who follow Kp, geomagnetic storms, and space weather — without the clutter.

This is a full rebuild of Planetary K-Index.
• Clearer Kp home screen with scrubbable bars, conditions, and 24h forecast
• Expanded NOAA SWPC charts (station K/A, geospace, ACE, aurora, and more)
• Europe · GFZ: official nowcast charts, Hp30, daily plots, Bartels, plus Poland INTERMAGNET (Belsk & Hel)
• Pull to refresh on live data and chart screens
• Legacy journal viewer for notes saved in older versions
• Fresh look, website, and privacy policy at planetary-k-index.org
Thanks for sticking with the app — if you follow Kp or space weather, we’d love a review.
