With solar minimum near, the sun continues to be surprisingly active
Between January 15th and 20th, the sunspot unleashed two X-class solar
flares, sparked auroras as far south as Arizona in the United States,
and peppered the Moon with high-energy protons. Lunar astronauts caught
outdoors, had there been any, would've likely gotten sick.
So much for the quiet sun.
It almost happened again last month. On April 25, 2005, small sunspot
emerged and--déjà vu--it grew many times wider than Earth in only 48
hours. This time, however, there were no eruptions.
