    Next 24 h

    Conditions are expected to remain quiet throughout the next 24 hours. The K-index will likely fluctuate between 0 and 2 as no significant solar wind structures or coronal mass ejections are anticipated to impact Earth’s magnetosphere.

    🌌 Aurora

    Aurora visibility is not expected at mid-latitudes.

    more

    Observers in high-latitude regions may see minimal activity, but there is no forecast support for displays in lower latitudes.

    👁 Watch for

    Monitor the development of active regions, particularly any increase in magnetic complexity, which could raise the current 10% probability for M-class solar flares.
