Additional Comments

There was a weak enhancement to the solar wind early this morning, indicating the possible arrival of a Coronal Mass Ejection (CME). Effects from this are expected to wane during the first forecast interval. Some further ACTIVE periods possible due to coronal hole high-speed stream influence, with a slight chance of this increasing to STORM G1 levels.
There are currently no Earth-directed CME's in the available imagery, QUIET geomagnetic conditions are expected overall.
