Belt of Venus

This post is not about birds, nor is it about a visit to a harbour side bar.  The Belt of Venus is a astronomical/atmospheric phenomenon. It goes hand in hand with The Earths Shadow.

I only found out about these two things a couple of weeks ago.  I had seen them of course but did not realise what they were or that they had a name.

For over sixty years I have been in the dark.

It was Margaret who told me about them.  She innocently asked at a meeting of Fraserburgh Photographic Society a couple of weeks ago if I had heard about them.  I had to admit that I hadn't a clue what she was talking about.

Margaret told me that the Earths Shadow is just that.  It can be seen just before sunrise and just after sunset on a clear day.  It is the shadow that the Earth itself casts on its atmosphere. This shadow is often visible from the surface of the Earth, as a dark band in the sky near the horizon.  The Belt of Venus is an atmospheric phenomenon seen at the same time  The observer sees a pinkish glow that extends roughly 10°–20° above the horizon.  So you look for them above the horizon opposite the sunrise/set.

On Thursday I was able to photograph both the Earths shadow and the Belt of Venus on my morning walk.  I had the added bonus of being able to include the moon in one of the shots.

Margaret and Alfie had just come back from a cruise around the Caribbean and up the Amazon.  One of the cruise lecturers was a NASA scientist.  He had explained about the Shadow and Belt in one of has talks.

So the Earths Shadow and the Belt of Venus are as easy to see on a clear day.  It's not rocket science, or is it?

I did manage to get some bird photos as well
