I got a call from my life partner to look at the moon last night. When I looked at it, at about 19:30 I recalled how much we look at something but never notice it. So I paid particular attention to the patterns on the moon and noticed the position of "the 2 fingers" (just my way of ref) in the upper left quarter. (Observing the moon from South Africa - southern hemisphere is slightly different from the northern hemisphere.)
This morning on 15th August at about 07:30, driving to work, noticing the moon as it descends on the western horizon, I realized the difference: It seems to be approximately 70-90 degrees tilted from the expected state. I expected to see the upside-down of last nights quarter in the lower right quarter, but appeared on its side in the lower left quarter.
I've grabbed some pictures off a website to put together a visual representation of what I saw.
