GEOMAGNETIC STORM WATCH (G1-CLASS): Yesterday, the sun launched a coronal mass ejection (CME) toward Earth. Forecasters are divided on when it might arrive–sometime between midday on March 27th and early March 28th. The impact could spark minor G1-class geomagnetic storms with equinox auroras boosted by the “Russell-McPherron effect.” Full story @ Spaceweather.com.
