    STRONG SOLAR FLARE: The magnetic field of sunspot AR1719 erupted on April 11th at 0716 UT, producing an M6-class solar flare. NASA's Solar Dynamics Observatory recorded the explosion's extreme ultraviolet flash. Coronagraph images from the Solar and Heliospheric Observatory show a CME emerging from the blast site. The expanding cloud will probably deliver a glancing blow to Earth's magnetic field late on April 12th or more likely April 13th. Stay tuned for updates about this significant explosion.
