over Payson Arizona November 9th, 2004
to 4am in 15 minute increments
is a complete run of Aurora Cam images taken from dusk to dawn
with our automatic robotic camera system. Aurora is quite rare
in Arizona, but apparently not as rare as the textbooks lead
us to believe. While we missed Sundays big display because of
much rain and very dense clouds, we were treated to this equally
brilliant display on the evening to morning of the 9th.
Here is a selection
of images from the above series that are clickable and can be
to 640x480 inside.
Note the shifting red and green glows.

time superimposed. The display elevated in intensity for the
most part all night until about 1 to 2am, where it peaked, then
fell off slowly by dawn. This can be seen in the sequence below.|
|Here is the complete
index print from the roll of 36 exposures we took that night
showing the progress in exact 15 minute intervals starting at
7pm, and lasting until 4am. You can easily see a layers of green
and then more reds on top of the main glow to the north.|
