QUIET
Geomagnetic conditions are currently quiet following the recent G2 storm, with the planetary K-index holding steady at 1.7. Despite the quiet geomagnetic state, solar activity remains elevated due to a high F10.7 radio flux of 197 sfu.

Next 24 h
Geomagnetic conditions are expected to remain quiet with Kp levels hovering near 2.0 throughout the next 24 hours. There is a moderate 25% chance of M-class flares as the active regions continue to evolve across the solar disk.
🌌 Aurora
Aurora activity is currently restricted to high latitudes.

There is no expectation of visible auroras at mid-latitudes (40-60°N) within the next 24 hours.
👁 Watch for
Monitor AR4505 as it approaches the western limb, as the evolution of its magnetic structure could trigger C- or M-class flares.
