For all those who may wish to know but don't their will be a lunar eclipse on the 21 of feb which will start after midnight.
For all those who may wish to know but don't a lunar eclipse happens when the sun and the moon are on opposing sides of the earth preventing any direct light from the sun hitting the moon ,however all is not lost because the earth atmosphere bends the red part of the spectrum onto the moon which is sitting in the shade which can turn the moon a beautiful shade of red.

Thank you, Micky. I shall watch out for that.

I noticed a very thin sliver of illumination on the Moon this morning as it passed just above the Sun at dawn this morning.
It was obvious that an eclipse was not far off.

Syphrum. what you have posted just does not make sense. Over the last three days the moon has been a thin crescent vewable early evening after sunset and it should not be visible (or above the horizon) at dawn.
The only bright object visible around dawn low in the sky near the sun is Venus. unless you are talking about five or six days ago when the moon was a waning crescent.

I meant early evening of course as you pointed out !

Your second statement about it being easily visible from the waxing crescent moon that an eclipse was likely is also wrong. You could not know that an eclipse was likely without knowing the precise dates and times of node crossing in the orbit of the moon using precise positional and timing measurements of the crecent moon against the sky.
