Additional Comments

Geomagnetic activity is expected to remain at predominantly QUIET levels throughout the forecast.
A coronal mass ejection (CME) associated with a filament eruption observed around midnight on the 26th Jan might result in a glancing blow during the second forecast interval, causing some ACTIVE and possibly brief STORM G1 periods.
Relatively large coronal hole can be observed in the northeast of the solar disc and will be monitored for possible influence in the coming days.
Time of forecast: 27 Jan 2025
