Hi George/Lu: Thanks copy of email from
yonder! Rather than shorten it or clog the Roar I suggest that George make
about 25 copies and distribute these at one of our meetings.
George, you can announce receipt of the
email from Sara as part of the meeting proceedings. What say
you?
Bill
P.S. It is so good that Sara is making the effort
.. very refreshing.

28
SEVERE SOLAR ACTIVITY: One of the most
powerful solar flares in years, a remarkable X17-category
explosion, erupted from sunspot 486 this morning at approximately 1110 UT. A
strong solar radiation storm is in progress. (Click here to learn
about the effects of such storms.) The explosion hurled a coronal mass
ejection almost directly toward Earth. When it left the sun, the cloud was
traveling 2125 km/s (more than 4 million mph). The CME could trigger bright
auroras when it sweeps past Earth perhaps as early as tonight.

Above: This SOHO coronagraph
image captured at 12:18 UT shows the coronal
mass ejection of Oct. 28th billowing directly toward Earth. Such clouds are
called halo
CMEs. The many speckles are solar protons striking the coronagraph's CCD
camera.
Sky watchers should be alert for auroras
tonight and tomorrow. High-latitude sites such as New Zealand, Scandinavia,
Alaska, Canada and US northern border states from Maine to Washington are
favored, as usual, but auroras could descend to lower latitudes when the CME
described above sweeps past Earth. [gallery]
