2018 Feb. 25 ~ The Waxing Gibbous Moon [CLOSE-UP]

******************************************************************************

Photographed from mid-town Toronto, Canada, at 18.43 EST (Moon altitude: 54° | Sun 7.6° below the horizon)

* Temperature 5° C.

 

Although this evening was very clear, there was a persistent gusty wind from the west, which made it difficult to keep the telescope steady during the ten subframes that make up this image.

 

Here the Moon, gliding through the constellation Gemini (The Twins) was 78.7% sunlit, on its way to its full phase in the early evening of March 1 (four days from now).

 

Although it is subtle, some colour can be seen on the lunar disk, particularly in the Moon's so-called maria ("seas"), which of course are lava plains and not water.
