Additional Comments

Geomagnetic activity remains QUIET and this is likely to continue until the start of the second forecast interval when we are expecting see the arrival of a glancing blow from the Coronal Mass Ejection on the 23rd. ACTIVE conditions are likely and there is a chance we could see an isolated period of STORM G1. The effects of this CME are anticipated to persist into the third forecast interval when we may continue to see some further ACTIVE periods. We cannot rule out the possibility of a further isolated period of STORM G1 on day three.
