Solar Sphere vs Sol Clock

The Solar Sphere provides current value of Kp-index derived from the NOAA Space Weather Prediction Center using data from multiple ground-based magnetometers. Also, current solar images are available in 4 different high resolution formats. The Kp-index quantifies solar disturbances in the horizontal component of earth's magnetic field with an integer in the range 0-9 with 1 being calm and 5 or more indicating a geomagnetic storm. For drone flyers, please only fly on solar KP Index less than 5.
