It looks like the real event occurred last night, but don't rule out a
display for tonight. I will be paying attention to the "Kp Index", which
is plotted at a three-hour interval at:
http://www.sec.noaa.gov/rt_plots/kp_3d.html
It reached 8 (on a 1 to 9 scale) during last night's aurora. Chris Schur
has recently been trying to correlate aurora visibility from Payson with
this index. I think he said he has picked them up photographically when
it is as low as 6. Maybe Chris will be able to add to this discusion.
Lots of good photos from last night at spaceweather.com. See:
