I wonder if anyone can give the precise reasons for why it gets
marginally
darker in the mornings for a week or so after Dec 21st. The late
Michael
Hunt from Anglia TV gave a description as to why. However, this was now
over
20 years ago and I cannot remember the precise reasons. Apart from the
fact
it is due to the fact that the earth's rotation around the sun is not a
precise circle, despite popular belief that it is. I cannot remember
the
other reasons.
I wonder if anyone on this ng does know why?

Gavin, Google or similar on "Equation of Time".

This topic comes up quite often. The last time we discussed it here was
last December. Here is the thread as archived by Google.
