Multiple CMEs to Jolt Earth’s Magnetic Field This Weekend - Aurora Alert

Geomagnetic storms are likely on Dec. 16th and 17th when multiple CMEs hit Earth’s magnetic field. A new NOAA model shows three CMEs combining to form a single storm front striking in unison on Dec. 16th around 20:00 UT. All of the incoming CMEs were launched into space by sunspot AR3514, which has been flaring almost constantly since Dec. 13th. The most important CME is linked to the flare of Dec. 14th; that one alone should be sufficient to spark a geomagnetic storm this weekend. NOAA analysts have issued a watch for G2-class (Moderate) geomagnetic storms with a chance of escalating to category G3 (Strong). Aurora sky watchers should be alert for auroral displays when it is dark outside.
