Additional Comments

Solar wind speeds are currently slightly elevated, likely due to a weak connection with a coronal hole high-speed stream. A Coronal Mass Ejection (CME) that left the Sun on 20-Dec may give a glancing blow early on 24-Dec. Geomagnetic activity is anticipated to be mostly QUIET, with a chance of some ACTIVE spells and a possibility of this increasing to STORM G1 levels, should the CME arrive during the first forecast interval.
