I spotted that too, they must have changed some image data in the last few days. I assumed at first that Cornwall was in winter, maybe it is. They've ruined what had been a spectacular view of Brunel's Tamar bridge, you can still see half of it. The shadow it cast was quite amazing, now you can only see half of it and it doesn't join properly. I was also a bit hacked off that the data for Cambridge is now older and a bit poorer quality. I don't understand why this happens.
