Hi Chris,
Maybe not South America, but if you go to www.skippysky.com.au now,
you will see Cerro Tololo and a full set of data.
Gotta be pleased with that!

Hi Chris,
Have a look at http://www.skippysky.com.au/2008/South_America/
I've done a 10x10 degree box around Cerro Tololo.
The numbers in the filenames are the number of hours forward from the
start of the dataset.
The title on each image will be more informative.
Give me a day or two to amend the SkippySky webpage.
Andrew
PS : and don't forget my half hour of imaging on the 4metre... ;-)

Hi Ken,
I'm familiar with Alex Danko's work, but you've missed this point that
I made :-
"Many existing astronomy weather forecast sites use the same data, but
present information for
only 1 specified lat/lon point at a time."
That's just what Clear Sky Chart does - one lone, single point at a
time.
My charts let you see what conditions are heading your way, and if you
should drove
N,S,E or W to get to a good observing point.
Besides which, Danko's charts ain't much good outside North America.
Andrew

Hi Chris,
> Any chance you can add South America to the list?
You really are out to blow my bandwidth quota...
But, what's it worth to you? A short imaging session on the 4M, object
of my choice..???

Any chance you can add South America to the list?

Not IDL related, but the Clear Sky Chart has most of the same info in
a much more compact form: http://www.cleardarksky.com/csk/
