Was there a CME in 2012?
The solar storm of 2012 was an unusually large and strong coronal mass ejection (CME) event that occurred on July 23 that year. It missed Earth with a margin of approximately nine days, as the equator of the Sun rotates around its own axis with a period of about 25 days.
What was DST for the July 2012 CME?
estimated Dst for the July 2012 storm. “If that CME had hit Earth, the resulting geomagnetic storm would have registered a Dst of -1200, comparable to the Carrington Event and twice as bad as the March 1989 Quebec blackout.”
What are the odds of a CME hitting Earth?
Future risk. According to a report published in 2012 by physicist Pete Riley of Predictive Science Inc., the chance of Earth being hit by a Carrington-class storm between 2012 and 2022 is 12%.

What is a CME solar flare?
Large solar flares, or coronal mass ejections (CMEs), are a routine type of space weather that occur when enormous blobs of plasma (electrically charged gases that make up all the stars in the universe) escape the sun’s atmosphere and ooze through space at hundreds to thousands of miles a second.
When was Quebec Canada hit by a CME wave?
The March 1989 geomagnetic storm occurred as part of severe to extreme solar storms during early to mid March 1989, the most notable being a geomagnetic storm that struck Earth on March 13. This geomagnetic storm caused a nine-hour outage of Hydro-Québec’s electricity transmission system.
How long does a CME last?
Q: How fast do the CMEs travel? A: A coronal mass ejection can make the 93-million-mile journey to Earth in just three to four days. This implies an average speed of about one million miles per hour.
