[photo-3d] aurora

[Bob Wier <wier@xxxxxxxxxxxxxxxxx>]

For those of you whom might be interested in trying to 
stereo photo auroras, looks like conditions are right .. here's
the alert. I'll see if I can upload the entire alert to the
files section on egroups.

    Gang,
    Tuesday, 3 major flares on the sun (an M-class and 2 X-class) were
    positioned such that the shock waves will impact the earth.  While we have
    seen several X-class flares this solar cycle, none have been positioned in
    the center of the sun to impact us this directly.  The next few days,
    starting thursday evening, should be very exciting as the shock wave from
    these 3 flares reaches us, triggering some major geomagnetic storms and
    possible auroral activity into the center of the U.S.  How strong of an
    effect we'll experience will become more obvious as the shock wave gets
    closer and satellites measure it's passage.
    
    If it triggers an extremely severe geomagnetic storm, then power grid
    failures, damage to satellites and things like that are possible as well.
    
    For QRPers/hams, the bands will be pretty much trashed for the duration
    of these geomagnetic storms, from around late thursday into the weekend.
    HF blackout conditions may also occur.
