Re: [APML] Images of Noctilucent Clouds

["Arne Danielsen" <arnedani@online.no>]

Thanks, Robert!

I have added a couple of animations of the clouds to my website as well. The
images for the animations where obtained using a digital SLR - so strictly
speaking they are OT for this list, but I felt it could be cool to show the
dynamics of the clouds. I'm running out of space on my ISP's homepage area
so I had to store the animation on a webserver I have running at home.
Unfortunately I have only a 2048/256Kbs line with the latter limiting the
download speed you will get. Thus you have to be a bit patient for the
download to finish.

14.-15.07.2004 AVI animation created from 263 images taken over a timespan
of 2h11.5m (21:33-23:44 UT):

of 4h22.5m (21:34-01:56 UT):
