Additional Comments

Geomagnetic activity is expected to increase during the first two forecast periods due to the coronal hole high-speed stream influence.
Coronal mass ejections (CMEs) associated with filament eruptions observed yesterday may give us a glancing blow this weekend.
Chances of ACTIVE and STORM G1 intervals are anticipated.
