My kingdom for a decent night's sleep!

What's wrong with this picture?

Blue sky at one o'clock in the morning is what's wrong with it!

Strictly speaking it's just before one o'clock, and I am also positioned more than two degrees West of the Greenwich meridian, so the sun hasn't quite reached perigee (I do hope that I am using the term correctly) but the law of the land tells me that it's Monday and who am I to argue?
