22° Halo ======== .. articleMetaData:: :Where: Manchester, UK :Date: 20050306 0106 CET :Tags: photography .. image:: images/halo.jpg :align: center :target: http://photos.derickrethans.nl/asmosphere/aab When flying into Manchester Airport `last week`_ on my way to the Sheffield LUG Seminar I noticed a rainbow coloured circle (actually, only a part of a circle) around the sun. I think it's part of a `22° circular halo`_ although I'm not sure. You can clearly see that it's darker inside the "circle". What is also unknown is why there is this bright white ray directly between the Sun and the Earth (the image is a bit rotated, so that's why it's not straight down). .. _`last week`: /fosdem_and_sheflug_slides.php .. _`22° circular halo`: http://www.sundog.clara.co.uk/halo/circular.htm
