Additional Comments

Solar wind speeds are currently slightly elevated, possibly due to coronal hole effects. This is not expected to cause a significant enhancement in geomagnetic activity, but some ACTIVE periods may be possible.
A slow moving coronal mass ejection (CME) was observed heading south-west early this morning. Early indications suggest there may be a slight chance of a glancing blow, but it's arrival is likely to be beyond the forecast intervals.
