Additional Comments

There is still a hint of some weak residual CME effects and coronal hole influence which has kept solar wind speeds at slightly elevated levels. These are anticipated to decline and be close to ambient levels for most of the forecast interval.
There will be a possible enhancement during the third period due to another small coronal hole which may cause isolated ACTIVE geomagnetic conditions.
