Aurora caused by arrival of Sept. 30, 2013 coronal mass ejection in the Central Oregon Cascade Mountains.
On Sept. 30, 2013, the sun released an Earth-directed coronal mass ejection or CME. On Oct. 2, 2013, the CME hit Earth’s magnetic field, causing a mild geomagnetic storm, which in turn caused aurora in both the northern and southern hemispheres. The geomagnetic storm caused northern aurora to appear further south than normal in more than a dozen northern-tier US states, including Oregon and New York. In the southern hemisphere, auroras were seen as far north as New Zealand.
