## What is Planetary?

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.

### 5/5 — Drone Saver

*2026-02-20*

I always use the app before flying any drone to make sure the connection is stable and uninterrupted.

### 3/5 — First screen is missing

*2024-09-20*

The first and main screen advertised in the screenshots for this app is entirely missing. That is the 3 day estimated PK graph. This the main thing I’m after.  The other graphs are all for specific locations in the Northern Hemisphere. We’re down south. The 3 day graph is a world average also based on stations down South.
Apart from this the app works as advertised.

### 1/5 — THEY ERASE DATA

*2024-07-07*

First of all, there is no way to reach the developer with issues. Gee whiz I wonder why. 

The main issue is they have a visual graph presentation of the K index and it’s various aspects. If I could attach photos….they I would show that they delete data, meaning, the graphs don’t comport day-to-day. They erase evidence they don’t like? 

Not sure what’s happening but we’ll never know: there used to be a way to reach the developer, but they no longer interact with their customers. Gee whiz, I wonder why.

### 3/5 — NO WAY TO REACH THE DEVELOPER

*2024-03-11*

and there are no instructions or explanations of a lot.

### 5/5 — Awesome!

*2019-08-20*

Very helpful app. I was looking for one to monitor solar weather. This is awesome!
