~Space Weather Update~ AR1492 ERUPTS, CME TARGETS MARS
ASTEROID FLYBY: Today, May 28th, newly-discovered asteroid 2012 KP24 is flying past Earth only one-tenth the distance to the Moon. Amateur astronomer Rolando Ligustri photographed the 26-meter space rock during the early hours of May 28th when it was about 350,000 km from our planet: image. Measurements of the asteroid's orbit confirm that there is no danger of a collision with Earth.
AR1492 ERUPTS, CME TARGETS MARS: The magnetic canopy of sunspot AR1492 erupted on May 27th, producing a long-duration C3-class solar flare and hurling a coronal mass ejection (CME) toward Mars. NASA's Solar Dynamics Observatory recorded the explosion's extreme UV flash:
Note the shadowy wave billowing away from the blast site. That's the 'solar tsunami' so often associated with the ejection of CMEs.
