Additional Comments

Solar wind speed is currently somewhat elevated due to residual Coronal Hole influence but this is expected to decline over the next few days. Solar activity has been low and there are currently no known Earth-directed CMEs.
Overall, we expect geomagnetic activty to be QUIET for the next few days, although perhaps there remains a very slight chance of a further brief ACTIVE spell early on day one.
