Seeing the light
Sunday, May 11th, 2008
I get many queries regarding the hours of sunlight that we experience at the base. At the moment, we only have a few more days of sunlight left before loosing the sun for the winter. Of course, because SANAE IV is ‘only’ at 72° south, we ‘only’ have 2 months of permanent darkness. The image above is a projection of the current sunlight distribution on the planet, updated hourly, with 3-hourly satellite weather photographs, so this is pretty much what the planet looks like right now. You can see a larger image here, and a more realistic (but poorer visualisation of Antarctica) spherical projection here, thanks to Die.net. I’ve also added this to my current weather page, so that it will be accessible following the links on the right of the blog at any time. Enjoy!
