Coronal mass ejections from the sun are expected to reach our tiny blue-green planet either today or tomorrow. While these flares could disrupt electronics and electrical infrastructure they are not expected to have any impact on our civilization.
According to Alan Thomson, head of geomagnetism at the British Geological Survey (BGS), "There's a feeling that it's not as intense as we first thought it might be. But it's possible still that it could be a large enough event for us to see the northern lights in the UK."
A set of more intense ejections could have huge impact on our modern world. It is possible that electronics world wide could be "fried." Imagine a world without electricity or any type of electronics. IMHO, scary.
The National Oceanographic and Atmospheric Administration (NOAA) said that three coronal mass ejections were the result of solar flares on February 13th, 14th and 15th.
