ICONIC ERUPTION: A huge filament of magnetism and hot plasma blasted off the sun's southwestern limb today, March 19th, at around 1200 UT. The eruption was not Earth-directed, but it was iconic. Just look at this snapshot recorded by NASA's Solar Dynamics Observatory:

SUPER MOON: Watch out for the Moon on Saturday night. It's the biggest full Moon in 18 years. Astronomers call it a "perigee Moon," and it raises extra-high perigean tides. Contrary to some reports, however, this event will not trigger any natural disasters. Science@NASA has the full story.
