GEO: ACTIVE

A/B (quiet)
Earth is currently experiencing a transition into geomagnetic storming, with the Kp-index rising to 5.3 and expected to reach G3 levels later today. This activity is the result of arriving solar wind conditions impacting the planetary magnetic field.
The planetary K-index has climbed to 5.3, indicating the onset of G1 geomagnetic storm levels. Solar flare activity remains subdued, with only low-level C-class events reported, while the solar flux is holding steady at a moderate 146 sfu. The magnetosphere is actively responding to current wind pressures, setting the stage for more pronounced disturbances.
The forecasted Kp 6.67 at 21:00 UTC is the most critical metric as it signifies a strong G3 geomagnetic storm, which may cause minor power grid fluctuations and satellite navigation interference.
Geomagnetic activity is forecast to intensify, peaking at G3 storm levels (Kp 6.67) around 21:00 UTC today. Conditions are expected to moderate rapidly thereafter, returning to quiet levels by 00:00 UTC on June 6th.
Aurora visibility is significantly enhanced, with displays potentially extending to mid-latitude regions (40-60°N) during the peak period this evening. Observers in these zones should monitor the northern horizon under clear, dark skies as the storm progresses.

Monitor the Bz component of the Interplanetary Magnetic Field; a sustained southward orientation during the peak window will be the primary driver for intensifying the auroral display.
