Aurora Watch

The Bz component of the interplanetary magnetic field (IMF) has been pointing south for the past several hours on Friday and this is helping to disturb the geomagnetic field (Kp4). A further increase to minor (G1) geomagnetic storming will be possible during the next 24 hours as a coronal hole stream is now beginning to flow past Earth. Aurora sky watchers at higher latitudes should be alert.
