Additional Comments

There are currently no Earth-directed CMEs. Solar wind speeds remain at background ambient levels with little influence observed from the southern extension of the northern polar crown coronal hole. For the first two forecast intervals geomagnetic activity is anticipated to be QUIET. The Earth is expected to encounter a high speed stream due to an equatorial coronal hole, which has now become Earth-facing, during the third forecast period which could enhance geomagnetic conditions to some isolated ACTIVE spells.
