SOLAR PRESENCE
  Time tag is followed by a blank, then a solar-presence symbol:

        '*'  Daylight (refracted solar upper-limb on or above apparent horizon)
        'C'  Civil twilight/dawn
        'N'  Nautical twilight/dawn
        'A'  Astronomical twilight/dawn
        ' '  Night OR geocentric ephemeris

LUNAR PRESENCE WITH TARGET RISE/TRANSIT/SET MARKER
  The solar-presence symbol is immediately followed by another marker symbol:

        'm'  Refracted upper-limb of Moon on or above apparent horizon
        ' '  Refracted upper-limb of Moon below apparent horizon OR geocentric
        'r'  Rise    (target body on or above cut-off RTS elevation)
        't'  Transit (target body at or past local maximum RTS elevation)
        's'  Set     (target body on or below cut-off RTS elevation)
 

 

Until we learnt to close the screens the moths would come and cloud the room with shadows.

Now, just a few late sleepers remain clinging to the mesh when day returns.

In the morning a brisk towhee turns up promptly, with an outsized baby who mews for breakfast wings. The supply of tasty, misguided travellers seems endless.

And round again,
from day
to night.

There, the stars were always invisible, and the sky was never dark. I coasted from one pool of lamplight to another.

Here, the moon and stars illuminate a new expanse. And when a falling tree brings down the power lines, night is simply black.

All you can do is wait,
holding your position;
hopeful that things will eventually work out.

And round again,
from here
to there.

At first the night was so immense
I needed a torch to stumble
to the gate.

This year I stand outside at midnight, charting my position by the scent of the hemlock, the whirring crickets, and the soft chomp of a passing deer.

A moth performs a slow circumnavigation of this vast world we share,
keeping the probable moon at his left, trusting he made the right decision.

And round again,
from dark
to light.
