Different Sky

Climbing the hill above our village, south towards Beaminster Down, I saw this sky and discarded my previously planned blips for a shot of it.

Trouble was, I took the photo from my car, on an empty road but I didn't want to risk stopping and surprising a driver coming around the bend; as a result my steering was a little erratic for a couple of seconds and it will have looked stupid to the couple coming down the hill – the vicar and his wife.

Then I got to our caravan and checked the battery level: 5.8v.  Not good.  I wonder if my having left the master switch live had anything to do with the drop from 12v . . . ?
