Additional Comments

Solar wind speeds have been declining as CME influence has waned although they remain elevated. There is still a chance Geomagnetic activity could become enhanced if Bz turns southward for a period of time which could result in some minor storm conditions.
An X4 class flare was produced from the same active region as the previous CMEs, however, this region has rotated away from a direct Earth facing position and any resulting CME will likely only have glancing effects. Further imagery and analysis are needed to determine any impacts.
A coronal hole high speed stream is expected to become geo-effective late during the third forecast interval which would result in further possible enhancements of geomagnetic activity.
