Additional Comments

We are currently seeing a mild enhancement in the solar wind speed due to the ongoing influence of a coronal hole high-speed stream. Those effects are expected to persist during the first and second forecast period, elevating the geomagnetic conditions to ACTIVE levels with chances of STORM G1 possibly up to STORM G2 intervals.
