Additional Comments

Solar wind speed remains elevated due to the ongoing influence of a Coronal Hole High Speed Stream. The effects of this HSS are likely to persist throughout the forecast period, although the chance of any significant geomagnetic activity will decline as the week progresses.
Overall, QUIET conditions with a possibility of some occasional ACTIVE periods are expected over the next few days. There is still a slight chance we could see a brief period of STORM G1, most likely during day one but this is uncertain.
