K Index


What is K-index?

The K-index measures disturbances in the horizontal component of earth’s magnetic field and the magnitude of geomagnetic storms. The K-index is an excellent indicator of disturbances in the Earth’s magnetic field.

How to Read the Chart

If K is green and are between 1-4, conditions are calm.  If you see red that means the K-index is between 5-9 and conditions indicate a geomagnetic storm.

Each bar represents a 3 hour block (staring at midnight and going to 3am UTC, the next bar is 3am to 6am UTC etc.).

The 1-9 value on each bar is calculated by reading ground-based magnetometers around the world and matching those curves to a calm day curve.

Why is it important?

Humans are generally more psychic and can perform remote viewing and other extended human capabilities better in calm conditions.

The planet systems affected by geomagnetic storms are the electrical power grid, spacecraft operations, users of radio signals that reflect off or pass through the ionosphere, and observers of the aurora.

What is a geomagnetic storm?

geomagnetic storm (commonly referred to as a solar storm) is a temporary disturbance of the Earth’s magnetosphere caused by a solar wind shock wave and/or cloud of magnetic field that interacts with the Earth’s magnetic field.

The disturbance that drives the magnetic storm may be:

  • a solar coronal mass ejection (CME)
  • a co-rotating interaction region (CIR)
  • a high-speed stream of solar wind originating from a coronal hole.

The frequency of geomagnetic storms increases and decreases with the solar cycle.

We are currently in Solar Cycle 25 which is predicted to peak around 2024. Solar cycles affect our moods, pineal glands, biological systems and even our mass society in indicators such as the stock market, conflicts and inventions.  Learn more about this fascinating topic on the NOC’s Solar Cycle 25 area.
