Thunder to west at 1323Z.

Fascinating accessory clouds include mammatus
from a detached anvil, pileus on large CU and
CB arcus SW to NW (threatening sky).

Switching off power for now,

Correction to time of thunder... 1223Z (and still
rumbling at 1340Z, now to north through northeast
and round to east). Very little rain here, in fact the
sun has shone quite strongly for much of the last hour
in between the anvils.
