Additional Comments

Solar activity is low and geomagnetic activity is expected to be QUIET.
The next expected enhancement in geomagnetic activity will be due to coronal hole currently passing the central meridian of the Sun. This high-speed solar wind stream may begin to arrive towards the end of the third forecast period. A glancing blow from a coronal mass ejection (CME) launched early this morning may also arrive around the same time.
