2018 Mar. 24 ~ The first quarter Moon
***************************************************************************
Photographed from mid-town Toronto, Canada, at 21.41 EDT (Moon altitude: 47° | Sun 31° below the horizon)
* Temperature 2° C.
Two nights after my previous Moon photo (see it here: www.flickr.com/photos/97587627@N06/40963125961), the first quarter Moon was riding very high in the sky above Toronto on a cool and breezy evening. Actually, the Moon had reached first quarter about 10 hours earlier, which is why the terminator (the dividing line between the sunlit and dark halves of the Moon) appears slightly bowed to the left in this photo.
We are used to thinking of the Moon as a grey, colourless orb in the sky, but this image shows that there are some colours, subtle though they may be, that are discernible especially in the lunar maria, which are cooled lava beds.
