Additional Comments

The solar wind speed is slightly elevated today, increasing chances of an isolated ACTIVE interval.
We expect the solar wind speed to decrease and remain at background levels for the second and third forecast periods. However, there is a small chance of enhanced activity during the second period due to a glancing blow from a CME.
