Hello everyone!

I just run into russian Electro-L weather satellite's images, which takes or took every 30 minutes an image of the full half-disk of the earth and the images are downloadable online. I checked the RGB images in a sequence and found that it shows that antarctica is in light during the "winter" months (2013 november-2014 february). How does that fit to Flat Earth Theory?
Also, are these images also corrupt or something? I tried to stretch these "fish-eye" images to panoramic, but failed. Also the sun's reflection is interesting.
You can find the images here:

Here are some images.

I find it very interesting, now checking the infrared images which shows the surface in dark too.
