Coronal hole faces Earth
Monday, 20 September 2021 19:03 UTC
A southern hemisphere coronal hole is currently facing our planet. The coronal hole stretches all the way to the solar equator and is sending a stream of high speed solar wind towards our planet.
Solar wind flowing from this coronal hole could arrive at our planet on Thursday, 23 September. Active geomagnetic conditions (Kp4) are very much possible once the solar wind stream arrives at our planet. The coronal hole is unfortunately not very large so we expect at most two days of enhanced solar wind conditions but it should be enough for periods with nice high latitude aurorae.
