Additional Comments

The anticipated coronal mass ejection (CME) associated with the X8.1 flare arrived yesterday. The solar wind speed is elevated due to lingering CME effects and a possible connection to a high-speed stream from a coronal hole. Further ACTIVE or STORM G1 periods may occur in the first forecast period before a return to QUIET levels.
