Additional Comments

Solar wind speeds were elevated over the weekend due to a connection with a coronal hole high speed stream. This caused an increase in geomagnetic activity, the effects from this are now waning as solar wind speeds are declining towards background levels.
A coronal mass ejection (CME) associated with a filament eruption lifting from the Sun on 01 March may give Earth a glancing blow late on 04 March. Increased geomagnetic activity up to STORM G1 levels with a small chance of G2 is possible should this CME arrive.
