Additional Comments

Solar wind speed remains elevated at around 550 km/s and is expected to slowly decline as Coronal Mass Ejection (CME) effects from the past 3 days continue to wane. Some enhanced geomagnetic activity could continue into day one and two with further ACTIVE spells possible and with a small but declining risk of a brief STORM G1.
A near-disk centre small filament erupted early this morning, 22-Jan. Early images from LASCO, STEREO and Solar Demon indicated a presence of a CME with a small Earth-directed component. Analysis is ongoing and the forecast will be updated tomorrow when there is more information available.
