SOLAR ACTIVITY INCREASES: Both sides of the sun are active today. On the farside, an explosion commencing around 0400 UT hurled a massive CME into space. On the Earthside, sunspot AR1686 unleashed an M1-class solar flare at 0754 UT: movie. This uptick in global solar activity could herald a period of stormier space weather in the days ahead. Stay tuned.
FARSIDE EXPLOSION: An active region on the farside of the sun exploded during the early hours of March 5th, hurling a bright CME into space. Cameras onboard the Solar and Heliospheric Observatory (SOHO) recorded the expanding cloud:

NASA's STEREO-Behind spacecraft is stationed over the farside of the sun, directly above the blast site. An extreme UV telescope onboard the spacecraft recorded a movie of the explosion. The responsible active region will rotate onto the Earthside of the sun in less than a week, which means geoeffective solar activity is in the offing.
