Additional Comments

The solar wind has been disturbed for the last ~30 hours due to the effects of a coronal hole high speed stream. The solar wind speed remains elevated but is expected to start to wane during the first forecast interval. Further ACTIVE periods are likely, with a chance for some STORM G1 periods, during the first forecast interval.
