Additional Comments

Effects from a coronal hole high speed stream are now beginning to wane, and solar wind parameters are expected to slowly return to background levels over the first two forecast intervals. Whilst solar wind speeds remain elevated there may be a chance for some ACTIVE periods during the first forecast interval, but geomagnetic conditions are expected to remain at mostly QUIET levels.
