A solar flare is an explosion on the sun's surface ranging from minutes to hours in length. The smallest ones are B-class, followed by C, M and X, the largest. Similar to the Richter scale for earthquakes, each letter represents a ten-fold increase in energy output. So an X is ten times an M and 100 times a C. Within each letter class, there is a finer scale from 1 to 9. C-class flares are too weak to affect Earth noticeably. M-class flares can cause brief radio blackouts at the poles and minor radiation storms that might endanger astronauts. A powerful X-class flare can create long-lasting radiation storms, which can harm satellites, and even give airline passengers flying near the poles small radiation doses. X flares also have the potential to create global transmission problems and worldwide blackouts.
In summary, four clusters of solar flares: B, C, M, X. Of the four, the X-Class flares are the most problematic. I have mentioned the Carrington Event in a previous post. It was probably an X45 event. In 774 AD, a solar flare ignited and was perhaps an X46 (ten or twenty times larger). At that level, it is capable of changing the accuracy of archaeological dating.
A primary method of dating items is by measuring the level of Radiocarbon 14C in an object. Radiocarbon dating hinges on the assumption that objects will absorb a consistent level of C14 and that the half-life of C14 is predictable. A significant proton event alters the amount of C14 absorbed, making things appear younger than they are.
Another aspect of this is that there is the assumption that the protective magnetic shield on Earth is consistently the same. In the last one hundred and fifty years, this shield has started to decrease, meaning that even less severe solar events will have an increased capacity to cause damage.
The second observation of interest is video is evidence that the magnetic excursions are phenomena that may have happened two hundred and fifty thousand years and beyond. While I assumed that most people would consider this possibility, there is evidence to prove this conjecture. If you reflect on the magnetic excursion cycle, it results from a massive dust cloud from the center of the Milky Way. Our solar system orbits through the plane of this cloud roughly every twelve thousand years. Whether it is just the accumulation of dust or interaction with the magnetic forces associated with this cloud, the sun responds with a massive ejection of material roughly every twelve thousand years. The Earth both takes an immense impact and may also have its spin altered.
The comet that killed off the dinosaurs was thought of as something coming from outside our solar system. What if it is the reverse. What if it was a massive Coronal Mass Ejection (CME) that created an asteroid of material hitting the Earth.
