A powerful M5.7 solar flare has erupted, potentially leading to visible auroras in the U.S. by May 13, 2026. This event follows a coronal mass ejection traveling at 650 kilometers per second.
The M5.7 solar flare originated from sunspot region AR4436 and peaked on May 10, 2026. While most of the solar material is expected to pass behind Earth's orbit, a glancing blow is anticipated by early May 13, 2026. NOAA's modeling indicates that this activity could result in G1 (Minor) geomagnetic storm conditions, which may push the aurora borealis further south than usual.
