More pictures from the last few days

It has been a tired few days for me trying to switch back from nightshift, so here are some pictures.

Sundogs!
Arctic Fox in a Snowbank (what I didn't put up are the two pictures I took of the wrong snowbank. I saw the fox, and then took a picture of the snowbank to the right. Twice, before I noticed...) This little guy lives around the station and one of his favourite spots is in a little hole in that snowbank where you can see him in the picture. I took this out the dining room window at the station.
This next picture, I did not take. It's in the folder Rodica gave me and I think she said Volodya took the picture. Anyways, this is what the fox looks like when you can actually see him! (He's really little by the way, about the size of a regular sized cat?)

Ozonesonde on a milk crate. The ring on the top is tied by a string to a weather balloon.

The yellow thing with the curly bits is the GPS. The flat metal strip on the right somehow measures temperature and pressure but I'm not sure how. The part that measures the ozone is inside. The clear straw you see sticking out the right side in the above picture sucks in air. It brings it into a tube with 2 solutions which transfer ions in the presence of ozone. It basically works just like a battery, so the sonde just measures the current, and can infer how much ozone there must be at that altitude. Nifty, eh?
