Additional Comments

The solar wind speed has returned to background levels, and the geomagnetic environment is expected to remain QUIET throughout the first forecast period. However, the combined effects of an Earth-directed CME, a low-confidence glancing blow from a second CME, and the influence of a northern coronal hole are anticipated to enhance the geomagnetic environment between the second and third forecast periods. This could potentially lead to geomagnetic conditions reaching STORM G1 levels.
