Additional Comments

The solar wind returned to background levels and the geomagnetic field was QUIET over the weekend.
Solar active region 14366 has grown rapidly and produced a series of M- and X-class flares over the past 24 hours. The largest event was a X8.1 flare peaking at 23:57 UT yesterday. This event has an associated coronal mass ejection (CME). The bulk of the ejecta is expected to miss Earth, however a glancing blow is possible on the 5th.
The geomagnetic forecast is expected to be QUIET overall with a chance of reaching up to STORM G1 if the CME arrival occurs before the end of third forecast period.
