On June 17, 2025, an X1.2-class solar flare erupted from Active Region 4114. The flare, which began at 21:38 UTC and peaked at 21:49 UTC, was captured by NASA's Solar Dynamics Observatory.
This powerful event, classified as an X1.2 flare, is the most intense type of solar flare. It originated from the active region 4114, which has been a prolific source of solar activity, including several M-class flares earlier in June. The energy from the flare can reach Earth in about 8 minutes.
The eruption may have an impact on Earth. A coronal mass ejection (CME) associated with a previous M8.46 flare on June 15, 2025, is expected to reach Earth on June 18, 2025, potentially causing a minor geomagnetic storm. This could lead to disruptions in technology and the possibility of auroras.
