 A CME hit Earth's magnetic field on Oct. 24th at approximately 1800 UT (02:00 pm EDT). Acording to analysts at the Goddard Space Weather Lab, the impact caused a strong compression of Earth's magnetic field, allowing solar wind to penetrate all the way down to geosynchronous orbit for a brief period between 19:06 UT and 19:11 UT. Earth-orbiting spacecraft could have been directly exposed to solar wind plasma during that time.

Christian Praetorius of Hafnarfjördur, Iceland took this picture at Lake Kleifarvatn using a Nikon D3, 3200 ISO, and 30 seconds of exposure.
