Weekend CME Produces Beautiful Aurora
Although the associated February 24, 2012 solar eruption provided quite a show, the accompanying coronal mass ejection (CME) that impacted Earth's magnetic field on Feb. 26, 2012 around 4:00pm EST (2100 UT) was weak.
However, it did finally cause beautiful aurora in high latitudes after starting out very modestly. Thomas Kast captured this image of aurora on Feb. 27, 2012 from Muonio, Finland. Image Courtesy of Thomas Kast.
