The dazzling, multicolored northern lights, visible in all but 9 of the
Lower 48 states Sunday night and arguably the most impressive here in
13 years, may not be the last of this cycle. While hardly a certainty, a
new aurora can't be ruled out over at least parts of the country
Tuesday night. The auroral ovals, the swaths of the atmosphere encircling the
planet's highest latitudes beneath which auroras are visible, are
normally found much farther north--in Canada and Alaska--or south near
NOAA space weather forecaster Michael Weaver says a geomagnetic storm
as intense as the one behind Sunday night's aurora occurs on average
only 4 times each 11-year solar cycle. While an "M-class" solar flare set
off Sunday night's celestial display, a second, more powerful "X-class"
flare Sunday afternoon could mean Earth's upper atmosphere may again be
showered by charged particles and that auroral displays might reappear
Tuesday night, says Triton College astronomer Dan Joyce.
