BIG SUNSPOT: The sudden emergence of big sunspot 1045 over the weekend has
caused a sharp uptick in solar activity. The active region has produced
three M-class and almost a dozen C-class solar flares since it appeared on
Saturday. The strongest blast, an M6-class eruption on Feb. 7th, may have
hurled a coronal mass ejection toward Earth. High-latitude sky watchers
should be alert for auroras in the nights ahead as a result of this
activity. Also, ham radio operators are picking up strong solar radio bursts
using shortwave receivers. Sample sounds and images may be found at
