Additional Comments

Solar wind speed is currently declining, and is expected to return to background levels during the first forecast interval. The solar wind may then become disturbed again late in the second forecast interval due to a coronal hole high speed stream, which could lead to some periods of ACTIVE conditions.
We may also see a glancing blow from a coronal mass ejection which may increase geomagnetic activity, with a chance for some isolated STORM G1 periods.
