Additional Comments

The solar wind speed is currently at background levels, and geomagnetic activity has been QUIET.
We do not anticipate any significant enhancement in solar wind speed during the forecast period. Geomagnetic activity is expected to remain predominantly QUIET. However, there is a low chance of isolated ACTIVE intervals during the second forecast period should a faint CME associated with an M-class flare arrive at Earth. Confidence in the arrival time remains low due to the very faint nature of the event.
