JANUARY 5TH - JURA MOUNTAINS 'CUP HANDLE' EFFECT

[paulastro]

Went out at 8.15 pm when I  saw indications there may be a thinning of the cloud, and stayed out until 8.50 and managed some glimpses of the Moon when the cloud broke near the Moon  briefly.  I was pleased I bothered as the 'Cup Handle Effect' was visible.  This is when the Jura Mountain tops are catching the morning sunlight, but the sunlight has not advanced across Sinus Iridium far enough to reach the base of the mountains.  This has the effect of making the Jura Mtns look rather like a cup handle clinging to the edge of the terminator.

Took a single frame at 8.45 pm, SW 80ED, AZ5, Olympus E-M5 Mk11, 1/25 sec at 400 asa.
