Additional Comments

Solar wind speed continues to decline as recent coronal hole effects diminish.
The next coronal hole high-speed stream is expected to arrive on 23-Feb most likely increasing the geomagnetic activity to ACTIVE/STORM G1 levels.
Although several coronal mass ejections were observed over the last few days, none of them are believed to be Earth-directed and any potential glancing impacts are expected to be minimal.
