Additional Comments

Solar wind speed is currently elevated due to ongoing Coronal Hole influence, but this should decline over the next day or so towards more ambient levels. A potential CME glance mentioned previously is now looking likely to have missed, and even if it is slower than anticipated any influence should be insignificant at this stage. The next High Speed Stream is due to become geoeffective later in the week and is outside the scope of this forecast.
Overall, geomagnetic activity for the next few days should be QUIET, although there remains a chance of an occasional ACTIVE period on day one due to residual Coronal Hole effects.
