Additional Comments

Solar wind speeds are on a declining trend as coronal hole influence, that caused some geomagnetic activity at the weekend, wanes. This will lead to QUIET geomagnetic conditions with the outside chance of some isolated ACTIVE spells.
Another small coronal hole feature may impact the Earth during the third period although this may only cause some brief enhancements.
