dailyloe.com – A significant solar flare, rated M5.7, erupted from the sun on May 10 at 9:39 a.m. EDT, originating from sunspot region AR4436. This event unleashed a coronal mass ejection (CME) that may impact Earth later this week, raising the likelihood of northern lights displays at high latitudes.
The active sunspot region AR4436 is now in Earth’s strike zone and will become more visible in the upcoming days. NOAA’s Space Weather Prediction Center and the U.K. Met Office indicate that part of the CME could graze Earth on May 13, potentially leading to minor geomagnetic storm conditions.
Solar flares are classified on a scale from A to X, with M5.7 being a powerful flare capable of disrupting radio communications. The recent eruption caused a radio blackout over the Atlantic Ocean, disrupting high-frequency signals used by aviators and mariners.
The eruption’s timing is significant for aurora enthusiasts, recalling the extreme G5 storm that occurred on the same date in 2024. That event marked the first of its kind since 2003, producing northern lights visible in unusually low latitudes.
While the current CME is not expected to generate a storm as intense as the one in 2024, a weak glancing blow could still result in minor geomagnetic activity later this week. Forecasters at NOAA and the U.K. Met Office continue to monitor solar activity for further developments.
