On Saturday night, having driven through thick fog, we camped at this spot - 56°51'18.53"N, 5°20'41.36"W (the joys of google earth in working such information out!) hoping to get an early start before climbing Gulvain the next day. At camp, it was a cold clear night that went down to -6 or -7 (at least) and the trees glittered with hoar frost illuminated by the shifting beam of my headtorch. This is a short video clip made that night (the quality is better when viewed directly from the Vimeo link).
There were some fantastic shooting stars in the sky too; it turns out that this was the Geminid meteor shower which reached it's peak on 13th & 14th Dec.
