Sky on Saturday - 1

Saturday, for some reason, always seems a difficult day for me to get a decent blip.  So I have decided to start a series of blips of the same piece of sky, on the same day, at roughly the same time of day, as a way of marking the changes of the seasons.  Unfortunately today's sky is a boring grey, but if I am going to be true to my own rules then the boring grey is as important as the brightest blue.
