Additional Comments

There may be a mild solar wind enhancement during the first forecast interval due to coronal hole effects. Geomagnetic conditions are expected to remain mostly QUIET, but there may be a slight chance of brief, isolated ACTIVE periods.
The was a filament eruption from the SE quadrant of the Sun early this morning. There may be a weak coronal mass ejection associated with this event, but it is not expected to lead to a significant enhancement in geomagnetic activity.
