Half an hour after sunset

That's a little before 6 pm. The days are getting longer quickly now. The weather has turned colder. It was -23°C in the morning, but much warmer in the afternoon (-9°C) and no wind, so where the sun shines, it doesn't feel so cold at all.

I tried to start a tractor in the afternoon to fetch wood from the forest, but the battery was dead. The sunshine doesn't help there!
