May 30 2012 Coronal Hole Emitting Solar Wind Directed towards Earth 2 HD

 
A large coronal hole is emerging over the sun's eastern limb. Solar wind flowing from the opening should reach Earth on June 6-7.
The energy that heats the corona and accelerates the solar wind originates in subphotospheric convective motions.
However, even after a half-century of investigation, the physical processes that transport this energy to the corona and convert it into thermal, magnetic, and kinetic energy are still not known.
CME C3 TARGETS MARS: The magnetic canopy of sunspot AR1492 having erupted on May 27th at 0551UT, producing a long-duration C3-class solar flare and having hurled a coronal mass ejection (CME) toward Mars, will hit the MSL spacecraft (containing Mars rover Curiosity) on May 31st at 0100 UT followed by Mars itself about 10 hours later. According to analysts at the Goddard Space Weather Lab.
