Surprised by the clear sky I looked north from J4 on the M3 (Farnborough) at
22.55 GMT last night and saw some white clouds which contrasted clearly with
the black ones still visible. I did not know whether the white clouds were
simply high cirrus still illuminated by the sun (the northern sky was not
completely dark of course) or whether they were indeed of the noctilucent
type. How would I tell the difference?
