Additional Comments

The solar wind speed is currently elevated due to the influence of a transequatorial coronal hole. This enhancement in solar wind speed is likely to increase geomagnetic activity during the first and second forecast periods. The solar wind speed will gradually return to background levels, decreasing the chances of activity by the third forecast period.
