Additional Comments

Solar wind speed remains around background levels and geomagnetic activity should be QUIET for the next day or so.
A Coronal Hole High Speed Stream is anticipated to become geoeffective later in day two and could enhance levels to ACTIVE with a chance of an occasional period of STORM G1 which will continue through day three.
The CME mentioned yesterday looks to be missing Earth, although there is a little uncertainty about a possible weak glance, however any possible influence is unlikely to be significant and could be coincident with the High Speed Stream.
