Planetary K Index (Kp) Products will be updated on or about November 14, 2022

On or about November 14, 2022, at 1700 Universal Coordinated Time (UTC), the National Weather Service will deploy an update to the Planetary K index (Kp), adding two decimals of precision. The Kp index is currently provided as an integer. The improved precision will more accurately reflect the state of Earth’s magnetic field and allow better correlation of this index with other indicators of geomagnetic activity. The change will propagate across ten products which incorporate or display Kp. The NWS Service Change Notice (SCN) provides more details and links to samples of the new versions of the products.
