Sunrise, Sunset.

I’ve looked at maps all my life, but never noticed that it gets dark earlier in the South East in summer than in the North West. Of course I know the Earth is tipped at an angle, something like 22° and I know that at the equator day and night are about the same length and that sunrise and sunset are about 6pm. But I hadn’t noticed the angle that the terminator of day and night is at.

As we are on the Greenwich longitude line I assumed the shadow would run straight up and down the globe. But of course it can’t be if the Earth is tipped. That also explains why we have seasons in the North and South hemispheres.

Sunset

The night draws in again

Sunset and its rosy glow is gone

Eight minutes before the sun set

Light travelling ultra fast,

Eight minutes to shine from sun to earth.

Energy in motion, then lost

Behind the hill

Night infects the light

It’s inky blackness sometimes reduced

By moon and stars

Or reflected light on clouds.

But the dark cannot hold as the earth turns.

Tipped slightly, seasons prevail North and south.

As spring arrives days grow longer

Now sunsets late or never

While equator stays the same

the North and South vary.

Sunset later every day till mid summer

Then decline.
