GEO: ACTIVE

A/B (quiet)
Earth’s magnetic field is currently experiencing a G2 (Moderate) geomagnetic storm. This activity is driven by an increase in solar wind speeds interacting with the magnetosphere.
The Kp-index has climbed to 5.0, triggering a G2-level geomagnetic disturbance. Solar flare activity remains subdued with only minor C-class events, and the F10.7 solar flux is currently at a moderate level of 127 sfu, indicating a stable solar disk despite the current geomagnetic unrest.
A current Kp-index of 5.0, which confirms that sufficient energy is being deposited into the upper atmosphere to generate G2 storm conditions.
Geomagnetic activity is expected to peak at G2 levels through 21:00 UTC today before beginning a gradual decline. By early tomorrow, May 16, conditions are expected to settle back to quiet levels as the high-speed solar wind stream passes.
Mid-latitude observers in northern regions of North America and Europe may see auroral displays tonight. Clear, dark skies away from city light pollution will provide the best opportunity for viewing as the storm progresses.
| Region | Location | Class | Flares C/M/X |
|---|---|---|---|
| AR4435 | N22W81 | Cao/B | 2/0/0 |
| AR4438 | N20W57 | Dao/B | 1/0/0 |
| AR4436 | N19W13 | Cao/B | 1/0/0 |
Monitor the Kp-index over the next 6 hours; a drop below 4.0 will signal the beginning of the storm’s conclusion.
