Solar activity remains stable with moderate flux and quiet geomagnetic levels
SOLAR: MODERATE
GEO: QUIET

Active Regions
5
X-Ray
A/B (quiet)

The Sun is currently in a period of moderate activity, characterized by stable geomagnetic conditions and a lack of significant solar flares. Earth’s magnetosphere remains quiet, with no immediate disturbances expected in the near term.

F10.7 Solar Flux
145.0
sfu · >150 = high activity

Solar activity is marked by an F10.7 flux of 145 sfu, indicating a healthy level of solar cycle progression. Five active regions are present on the disk, with AR4465 producing minor C-class flares. Currently, the geomagnetic field is settling following a minor increase in the K-index to 3.3 earlier today, now back down to 2.3.

Key Metric

The current Kp-index of 2.3 is the primary indicator that the geomagnetic environment is stable and poses no risk to power grids or satellite operations.

Geomagnetic conditions are expected to remain quiet, with the K-index likely hovering between 1 and 3 over the next 24 hours. Flare probability remains moderate, with a 40% chance of M-class events due to the magnetic complexity in current active regions.

🌌 Aurora Outlook

Aurora activity is currently low and restricted to high-latitude regions. Observers at mid-latitudes should not expect visible displays under these quiet geomagnetic conditions.

Monitor AR4465 for any sudden increases in magnetic complexity, which could raise the likelihood of an M-class flare impacting local high-frequency radio communications.
