Area climate forecasters at SWPC predict an opportunity of minor G1 geomagnetic storm circumstances (Kp 5) between 2 a.m. and 5 a.m. EDT (0600–0900 GMT) on June 20. (Kp is a measurement of geomagnetic exercise, with an index that ranges from 0 to 9; increased Kp signifies stronger auroral exercise.) You may sustain with the court forecasts and geomagnetic storm warnings with our aurora forecast live blog.
