Additional Comments

The solar wind speed has started to wane, and is expected to trend towards background levels through the first interval. Brief ACTIVE periods may be possible early in the first forecast interval, before a return to mostly QUIET conditions.
Another high speed solar wind stream may become geoeffective towards the end of the third forecast interval, which may enhance geomagnetic activity slightly.
A coronal mass ejection (CME) was observed early this morning (~0600UT) originating near centre disc. Imagery for analysis is currently limited, but it is likely that this CME will have an Earth-directed component, possibly late in the third forecast interval.
