I've been playing with the code that generates the satellite
pic on the OAFs mainpage. (I'm not actually sure that anyone
uses it, but WTH.) 

I've tried to indicate which way the clouds are moving. 
That bizzare blue streak on the image always has one end
over ottawa. The streak represents the path along which
clouds are moving towards ottawa (at least according to
my not-too-brilliant cloud-matching algorithm). 

I suppose I should draw it as a cute arrow or little chubby
iconic faces blowing wind, but I havent figured out how to do
such stiff the the graphics library ive got. 

Usually, that blue streak
will approach ottawa from the west, since thats where the
weather usually comes from. But when the weather is
nasty, clouds can approach from anywhere. Then, the streak may
come from the east or curl bizzarely. The algorithm I use wont
work when clouds are forming or disipating more than they
are being blown around by the wind. 

Its my hope that the blue streak will tell us if that tasty little
clear patch (hypothetical, certainly not tonight) is approaching
us or not. 

If this turns out to be useful, I can add a second streamline for,
say eguuleus observatory (assuming I can figure out exactly which
pixel it corresponds to).

Hey Attilla!!
Maybe when the wind is moving REALLY fast, the line could turn red!!!  Just like in the American attempts to explain hockey to the uninitiated!!  Then again, maybe not.....
Desparately seeking photons!

Neat stuff.  Count me as someone who looks at it each time I update the
page.  Not that I understand what I'm seeing, mind.
