Did you really take the picture of the Canigou from Marseille? Wow, that's a long distance! MartinD 08:48, 26 May 2006 (UTC)[reply]


Yes indeed! This is due to a mirage phenomenon, the image of the Mont Canigou being reflected by high altitude atmospheric layers. This mirage is visble twice a year, when the sun set exactly behind the Mont Canigou (i.e. the Canigou is exactly between the sun and the observation point). A straight line betwen Marseille and the summit of Canigou would go underwater. See http://www.canigou.univ-mrs.fr/ and http://astrosurf.com/canigou/ for more pictures, and some explanations (in french). Note that it is also possible to see the Mont Canigou when the moon pass behind it (see http://www.canigou.univ-mrs.fr/040601all.html for a very nice picture).

So it's not exactly Mont Canigou you see, but rather a mirage picture of it? MartinD 09:38, 30 May 2006 (UTC)[reply]

Yes, something like that. Or rather, the mirage of the silhouette of the Canigou (the sun being behind it).
