Here's a sunspot for you :-) Space Weather News for March 26, 2008 http://spaceweather.com Solar activity is surging. Three large sunspots have materialized and at least one of them harbors energy for strong solar flares. An M2-class eruption on March 25th hurled a coronal mass ejection (CME) into space and emitted radio bursts audible in shortwave receivers on Earth. NOAA forecasters estimate a 50% chance of more M-flares during the next 24 hours.
