Explanation:
There was something behind the clouds.
Upon close inspection, it was the
Moon,
which was hard to see yesterday around noon above the small village of
Cessy,
France.
But soon, it was not only
the Moon.
As expected, a bright dot suddenly appeared from behind the Moon --
the planet
Venus far in the distance.
Captured in the single
featured exposure, both appeared to show a
crescent phase.
The Moon's
crescent was quite slight --
with only about 10 percent of its face illuminated by
the Sun.
In contrast,
Venus's crescent was more full --
showing about 25 percent illumination.
Venus appeared brighter because it is nearer the Sun and because its
clouds are more reflective than the
dark lunar surface.
An occultation of
Venus by the Moon is visible
to only about 10 percent of
the Earth,
but in yesterday's event even most of that was experiencing
daytime.
