Additional Comments

Solar wind is now reaching ambient levels as the recent coronal hole influence wanes.
The high-speed stream from another small and more centrally located coronal hole is expected to reach Earth during the second forecast interval, increasing the chances of ACTIVE and brief STORM G1 periods.
Otherwise, predominantly QUIET geomagnetic conditions are anticipated.
