N.B. on movies.
The movies are in the standard Quicktime (™). If necessary, you can download the software adapted for your operative system, at the Apple site, specific for your nation and language.
Each movie has its code name, which reports in the order: the location, the two last digit of year, month, day and the hour ut (universal time) [locationYYMMDDu0000].
To start a movie QuickTime®, click on “>>>”, at the centre of the introductory photo.
If you have a problem to download the movie, try to click on [md]. The outcome depends on the software of your computer.
