Flower friday

There is a photo of this a few days ago but not close up, it is a daisy of some kind and it opens to the sun every morning and closes again when in shade.
This photo shows one in full glory and the other closing down for the night, they don't even look like the same flower.
I have had this flower in my garden for years and know it opens with sunlight, I have never noticed it in this half way stage before I started taking photos.
