Shape of the Earth's shadow

Lovely images John, out of curiosity, what made you think it would be more jagged ?
What I said was I thought the shadow was jagged, I expected it to be smoother, it just surprised me. Though its probably explainable by earths profile by the shadows of mountains amplified through our atmosphere. Not sure if I'm explaining that clearly. Either that or scattering of light is different through areas of our atmosphere, maybe due to particulates accumulating in different areas. Just a thought.

The first picture clearly shows what I was trying to explain. The shadow does slope more gently from the right and then angles "sharply" back to the left limb.
Would that be because, from our viewpoint on Earth, the Moon was passing through e.g. left of centre in the shadow?

This is a very interesting thread and discussion. Time to go back to my images and look for anomalies. :lol:

When I went out to see mid-totality better there was a rooster crowing in the distance as if it were the end of the world but there was a total lack of dogs barking, which one usually hears from the town at night. The usual nightsongs of the local birds were also absent.Many thanks for putting up those shots John ... well done on getting good skies for the event.

A friend of my Dad was saying to me last night that a flock of curlews that feed in the field near his house up from the village went all quiet during totality but then began their forlorn calling again during the partial phase. A very interesting observation as I've never seen any reports before of nature going quiet during a LUNAR eclipse.
Amazing to think that there is still so much to learn about the many facets of eclipses.
All the best,
John
