Extreme Solar Storm Hit Our Planet 9,200 Years Ago geoscience space science
“These particles — mostly protons — can eventually reach the Earth guided by the heliospheric magnetic field lines.”
“In the last decades, great attention has been dedicated to solar storms due to the high vulnerability of our modern society to such events.” “SEP events can, in fact, have serious repercussions on communication and power systems, satellite life expectancy and aircraft operations. For instance, during the so-called ‘Halloween storms’ of 2003, parts of Europe were left without electricity for several hours, and transformers in South Africa were permanently damaged, with enormous costs for society.”
“In addition, the life of astronauts in space could be endangered due to high radiation exposure connected to SEPs.”36They discovered traces of a massive SEP event that hit Earth during one of the Sun’s passive phases about 9,200 years ago. “This is time consuming and expensive analytical work. Therefore, we were pleasantly surprised when we found such a peak, indicating a hitherto unknown giant solar storm in connection with low solar activity,” Professor Muscheler said.“In addition to power outages and radiation damage to satellites, it could pose a danger to air traffic and astronauts as well as a collapse of various communication systems.
