Yesterday’s geomagnetic storm caused some great auroras
A CME hit Earth’s magnetic field on Oct. 24 at 1800 UT, sparking a strong (Kp=7) geomagnetic storm. Auroras were sighted in the United States as far south as Arkansas and California
Video 1: The SOlar Heliospheric Observatory (SOHO) captured this “coronograph” – so-called because the images block the sun, and only show the sun’s atmosphere, or corona. The coronal mass ejection (CME) that caused aurora to appear on the evening of October 24th begins when the counter in the lower left hand hits October 22, 1:36 (which translates to October 21, 9:36 PM ET).
