The planetary K-index is currently at 3.0, following a period of relative stability. Solar activity is characterized by moderate flux levels and a consistent presence of active regions. While current X-ray flux is quiet, the forecasted interaction with solar wind streams is expected to push geomagnetic conditions into active status shortly.

Key Metric

The Kp-index forecast of 5.67 indicates a G2 geomagnetic storm, which may cause minor fluctuations in power grids and satellite drag.

Conditions are expected to fluctuate over the next 24 hours, with a peak at G2 storm levels around 06:00 UTC before settling back to unsettled levels. A secondary increase to G1 levels is anticipated toward 12:00 UTC as geomagnetic instability persists.

🌌 Aurora Outlook

Aurora visibility is possible for observers at high latitudes and potentially reaching mid-latitudes during the peak of the G2 storm window. Observers should monitor the horizon in dark, clear conditions around 06:00 UTC.
