Moon Monday 4th November 2019 (later)

Here is the Moon later in the evening, near the horizon.

Why does it look redder?
Why does it look bigger?

It looks redder because, when the Moon is on the horizon, the light particles have to travel through more atmosphere to get to your eyes, and the atmosphere scatters the blue particles away from you, but not the red.

And no-one knows why it looks bigger, although the general consensus is that it is an optical illusion, by how the brain thinks of the relative size of objects to the ones around it. A bit like Father Ted's 'Small and Far Away'!

Time 22:08.
Distance 249,177 miles.
First quarter phase.
230 degrees SW compass point (azimuth).
Altitude 4.8 degrees.
