Blue sky from horizon to horizon

I do not remember ever seeing a totally blue sky without the merest wisp of a cloud in the UK before. That is how it was here today.
The blip is the result of pointing the camera straight up in earthdreamer's blipping ground - Shipley market place.
Not as interesting as his blips but I just wanted to record today and that is what it was to me - blue sky.
Although there was frost at 6am by 9 the sun was warm enough to lie out in. Unfortunately I couldn't do that as there were just too many 'must dos' to do.
PS. Must get the sensor cleaned!
