We had a very fine view of a tiny cresent moon tonight. I first
noticed it in the sky at about 20 degrees elevation a little
after 6:00pm local standard, only about 27 hours old.
At 7:30PM, as twilight deepened, it was visible near the western
horizon at about 10 degrees of elevation showing a very fine,
thin crescent; like the white part of a well manicured man's
fingernail held at arms length.  It took a little walking to
find an unobstructed view with the moon at this low altitude.
Through the binoculars, craters on the thin illuminated strip
near the western edge of the moon stood out in bold relief.
By naked eye, the whole disk of the moon was visible, and in
binoculars, the contrast between the mare and the highlands
could easily be seen in the dark area.  
I suppose as the moon gets closer to full, it's too bright to
make out these features by earthshine.  I'd also guess that
the earthshine is probably brightest during new moon; new moon
means full earth on the moon, full moon = new earth on the moon?
