LD 291 Helicopter in the wintry hills

Late this afternoon I heard a sound coming up the loch and a moment later  the AirSea Rescue helicopter from Prestwick appeared going north.  

I had just been wondering what my blip for the day would be  and luckily  I managed to get a few pictures with my iPhone, of which this was the best, showing as it does not only the helicopter itself but also dark falling amongst the wintry hills.
