The 23rd December

Here we have a very good weather without wind. Probably too good, because I need a wind from eastern or south-eastern direction to start the air filtration. Yesterday and the day before yesterday,  we were busy with the field training (crevasse rescue, etc). Sanne, the army field guide, has developed a much more intensive program for us. We really went into crevasses and other members of the group had to pull us out. 
Now, I work with the workshop to adjust some installations (the small measurement chamber for the Fluorpen, etc), and I unpack boxes from the last year (with the vacuum pump etc.).
