The National Aeronautics and Space Administration (NASA) reported that the Sun erupted with this CME on Friday March 15, 2013, at 2:54 a.m. Eastern Daylight Time (EDT). See the images, above, taken of this CME.
The NASA space probe Solar Terrestrial Relations Observatory (STEREO) and the NASA/European Space Administration (ESA) space probe Solar and Heliospheric Observatory (SOHO) observed and recorded the CME event.
And, weather forecasters with the National Oceanic and Atmospheric Administration (NOAA) state that there is a 70% chance that polar geomagnetic storms could occur beginning on March 17th or the 18th at the latest.
The geomagnetic storm occurs when a CME interacts with the Earth's magnetosphere. This interaction can adversely affect electronic systems on satellites circling around the Earth and on various electronic systems based here on the surface of Earth.
Auroras could be produced by this event, sky watchers may see them in the high latitudes and even possibly people in the middle-latitudes might observe them, too.
