Additional Comments

The solar wind speed is currently at background levels, and geomagnetic activity is expected to remain low during the first and most of the second forecast periods. The influence of a coronal hole (CH42) is expected to become geoeffective late in the second period or early in the third period, increasing solar wind speeds, with geomagnetic activity likely reaching STORM G1 levels.
