Additional Comments

Solar wind speed remains elevated due to ongoing coronal hole influence but this is anticipated to start to decline over the next day or two. A CME observed on the 18th is likely to miss Earth, but we can't rule out a small chance of a weak glance, probably towards the end of the first forecast interval should it occur although any effects are unlikely to be significant.
Overall, geomagnetic activity should be QUIET for the next few days with a possibility of an occasional ACTIVE period due to residual coronal hole effects and any weak glance from the aforementioned CME.
