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 and the first response was from dear old Bill
Giles on the BBC site. "Both are rare clouds and can only be seen, briefly,
at sunrise and sunset when all the other lower clouds are in shadow." Just
checked our sunrise time for today and its 0748. How long they last after
sunrise I couldn't say - but I saw it. I couldn't honestly say what the
exact time was, other than I left home before 0800 and observed it within a
couple of minutes from the Wolds top.
