The northern hemisphere polar coronal hole which has an extension southwards has been facing Earth the past few days. A solar wind stream flowing from this coronal hole is expected to influence our planet in the coming three days. Geomagnetic conditions up to a maximum of Kp4 (active geomagnetic conditions) are possible starting today up till Wednesday (20 January). Solar wind speeds of well over 500km/s were observed last month when this same coronal hole faced our planet.
