Additional Comments

In the past 24 hours, the solar wind speed remains at the background level, showing relatively minimal variations. A brief ACTIVE period was due to the vertical component of the interplanetary magnetic field remaining in a negative direction for around two hours.
High-speed wind stream from a recurring coronal hole is expected to enhance geomagnetic activity to ACTIVE conditions at the end of the first forecast interval, and the majority of the second forecast interval, with a chance of STORM G1 occurring. Isolated ACTIVE conditions are expected in the third forecast interval.
