A powerful M5.7 solar flare erupted from the sun on May 10, unleashing an impressive coronal mass ejection (CME) that could deliver Earth a glancing blow later this week and potentially spark northern lights<\/u><\/a> displays at high latitudes.<\/p>\n

The eruption peaked at 9:39 a.m. EDT (1339 GMT) from sunspot region AR4436, now rotating into Earth’s “strike zone” on the sun<\/u><\/a>‘s northeastern limb. As the active region swings further into view over the next few days, any major flares or CMEs it produces will have a greater chance of being directed toward Earth.<\/p>\n

While most of the recently launched CME appears to be racing east of Earth, NOAA’s Space Weather Prediction Center<\/u><\/a> and the U.K. Met Office<\/u><\/a> say part of the expanding plume of solar material may still brush past Earth around early May 13. If that happens, it could trigger minor (G1) geomagnetic storm conditions, enhancing aurora displays across the northern U.S. and the U.K.<\/p>\n
