Sun Storm to Slam Earth

On Monday (Dec. 26), the sun unleashed a massive eruption of solar plasma known as a coronal mass ejection (CME). The CME's fast-moving charged particles should squarely strike Earth's magnetic field at about 3:20 p.m. EST (2020 GMT) Wednesday, give or take seven hours, according to the website Spaceweather.com.

The particles from another CME could deliver a glancing blow to our planet a few hours earlier on Wednesday, Spaceweather.com reported.
