One of
the largest solar flares of the decade exploded out from the sun just last
Thursday. Tons of solar particles shot
into space directly at earth, and with that speeding shower came the promise of
Aurora.
Aurora! They
never fail to take my breath away. They
are one of the magical and mysterious phenomena of our world. Solar particles get trapped in the magnetic
fields around the planet, and then ionize in those high and rarified regions of
the atmosphere to form glowing curtains and waves that keep deep northern and
deep southern sky-watchers fascinated for long night time hours. The resulting fire in the sky is sometimes
colored lights that shimmer and stream and shift.
Reports
from this last event were promising. Even
the scientists at the south pole were excited.
Aurora australis is more rare than borealis because of the way the
magnetic fields are shaped there. By
Saturday, a brilliant Aurora australis was taking its place above the horizon, holding great promise for a striking borealis in the north.
I've seen
northern lights perhaps six or eight times
in my life, and the memory of them is indelible. I once saw them as far south as the greater
St. Louis region, which was my hope this time.
It's been 14 years since my last Aurora and this was a strong enough
solar flare to push them into the mid latitudes.
But alas,
the city lamps and humidity were too dominant.
I looked six or eight times at various hours of the night for the past
week and disappointedly saw nothing . . . nothing but a smear of high pressure sodium lights
against the horizon.
