watched clouds (Crowes Landing)

We saw iridescent clouds from the dock. Opalescent colours, aquamarine and pink. Then it faded as the Sun set. Didn't get my camera.

Watched for sundogs. None.

Curiously, Frank had sent out a note on the RASC TC forum earlier: "Today (Sunday) is the sort of day when various unusual cloud phenomena, such as halos and ice crystal phenomena, waves, and iridescent clouds, are possible to appear."

I also wondered if the distant cirrus-like clouds were actually extreme high-level clouds that would become noctilucent. They exhibitied many of the tells: criss-cross streaks, fast ripples, slow moving. I considered it possible for these types of clouds to form at sunset and remain, catching light from the Sun as it dipped far below the horizon. I'll have to look into that...
