We had pretty good visbility here on the South Coast at sunset - I watched
Jupiter set amongst the trees. By 1900, however, it did not seem quite so
clear and I recorded "Moderate" rather than "Good".

Also noticed here after sunset was a distinct yellow glare to the SW with a
purple top edge, later fading to a red/purple band along the horizon. This
almost certainly due to aerosols from that volcano which blew in the
Aleutians a couple of months ago.
