reminded some observers of Solar Minimum, sunspot numbers are bouncing

over the sun's eastern limb is driving the sunspot number back up to

*POSSIBLE EARTH-DIRECTED ERUPTION:*A solar magnetic filament erupted on 
Halloween night, carving a "canyon of fire" in the sun's southern 
hemisphere. NASA's Solar Dynamics Observatory recorded the debris as it 
slingshot into space:

A boomerang presentation of the Halloween eruption.

The walls of the canyon are at least 10,000 km high and 10 times as 
long. Fragments of the magnetic filament may soon emerge from the blast 
site in the form of a CME. Fresh data from SOHO coronagraphs will soon 
reveal if it has an Earth-dorected component.
