Try asking the pprune member sharpshot
I have no idea who they are, but they seem to be a photographer. (search on their user name for some of their PPRuNe posts.)
Another thought is to go to
http://www.photo.net/
and ask there in one of their forums. A number of professional photographers use the site.
Ask NOAA too.

Best of luck.
