Additional Comments

Solar wind speed continues to slowly decline and geomagnetic activity has been QUIET overall, however the anticipated arrival of a glance from the CME observed on 3rd June, potentially combined with a Coronal Hole High Speed Stream may enhance geomagnetic activity to ACTIVE levels over the next couple of days and we could potentially see some periods of MINOR STORM (G1) later on day one and into day two should the effects of these combine. Any CME or High Speed Stream influence should decline towards the end of the forecast period going into next week.
