The big sunspot known as Active Region 1515 (AR 1515) erupted on Monday, July 2nd, at 10:52 UTC (6:52 AM EDT). The eruption produced an M5.6-class solar flare that nearly reached X-class strength.
A pulse of x-rays and UV radiation from the flare illuminated Earth's upper atmosphere, producing waves of ionization over Europe. Such waves alter the propagation of low-frequency radio transmissions. The eruption also hurled a coronal mass ejection (CME) into space, but not directly toward Earth. The south-traveling cloud could deliver a glancing blow to our magnetosphere on July 4th or 5th. Stay tuned...
