But surely at 0800 the sun is above the horizon. IIRC you only see
nacreous cloud when the sun is below the horizon.


Interesting point. Googled it...


So did I and found a few references to the sun being something like 5 to
10 degrees below the horizon. Now 5 degrees is 20 mins with sun coming
straight up. It will be longer with the sun rising at an angle.

As it was small patch could it have been a sun dog?

Thanks for the suggestion Dave.
I don't believe it was a sun dog. It was a genuine patch of bright cloud,
and a high one! When I say small it was significantly larger than a sun dog,
but one isloated cloud.
As I travelled south then south west over a couple of miles, the cloud took
on the distinctive look of a nacreous cloud, presumably with the change in
angle.
I'll stand by my original report, until an alternative option is given that
I can relate to!!
