SOLAR ACTIVITY: In recent days the Boulder sunspot number has rocketed to 339, its highest level since July 2000. At least one large sunspot group has a complex magnetic field that could harbor energy for powerful solar flares. Forecasters estimate a 20% chance of an X-class eruption during the next 24 hours.

AURORA WATCH: An interplanetary shock wave buffeted Earth's magnetosphere Tuesday morning and another may be following close behind. A coronal mass ejection that left the Sun on March 25th will arrive late Tuesday or Wednesday and possibly trigger additional geomagnetic disturbances. In recent days Alaskan sky watchers have enjoyed some of the best auroras of the current solar cycle. Check out our gallery of aurora photos for the latest images.
