Put on your tinfoil hats, because the sun just had an indigestion. According to NASA, this "spectacular coronal mass ejection should deliver a glancing blow to Earth's magnetic field during the late hours of June 8th or June 9th".
The CME was accompanied by a medium-sized solar flare and a minor radiation storm. The event was captured by all the satellites of NASA's Heliophysics missions: The Solar Dynamics Observatory, the Solar and Heliospheric Observatory and the two Solar Terrestrial Relations Observatory space probes.
Does this mean we are all going to fry like bacon in the oven? No. But it may affect our satellites and communications today and tomorrow. What is for sure is that we will have some amazing pictures and videos of auroras soon.
