A very thin line of what looked to be cloud stretch from east to west, racing across the sky from north to south. I thought initially it was shadow until I noticed how long it. I say it was cloud because that is the only explaination I have, although when it did pass over the tiny bit of blue sky we have it seem to vanish.
Took a couple of pics, sorry they are not very good. I didn't think I would have time to dash in and get my camera, so used my phone instead.

Has anyone seen this before? Can anyone explain what it was and why it happens?
Any thoughts would really be appreciated.
