Coronal hole faces Earth

A large northward extension of the southern hemisphere polar coronal hole is currently facing our planet.

Solar wind flowing from this large but patchy coronal hole could arrive at our planet tomorrow, 12 July. Active geomagnetic conditions (Kp4) are possible with a slight chance of minor G1 (Kp5) geomagnetic storm conditions once the solar wind stream arrives at our planet. This same coronal hole faced us during the previous solar rotation and managed to cause a brief 3-hour period of minor geomagnetic storm conditions on 15 June. Due to the size of this coronal hole we expect the resulting coronal hole solar wind stream to influence our planet at least three days spanning 12 to 14 July.
