Additional Comments

The solar wind speed is currently at background levels, and geomagnetic activity has been QUIET over the weekend.
We do not anticipate any significant enhancement in solar wind speed during this forecast. The only exception is a faint CME associated with an M-class flare that lifted off the Sun on Sunday 26 July. However, confidence in the estimated speed and arrival time remains low due to limited coronagraph imagery available and the very faint nature of the event. Should the CME arrive, it may do so towards the end of the third forecast period, increasing the likelihood of isolated ACTIVE intervals.
