This is the short story of a person who, rather casually, observed an anomaly orbiting the Moon. His web link allows for comments as well.
There are the usual
"it's a hair", "its a fiber", "aliens wouldn't be that stupid to build a ship that shape", "bad aerodynamics,
friction, too much fuel" type of comments. But when you go to the link, bare the following in mind.
1- a lens with the capacity of capturing images such as this (possibly 800mm lens) would blur anything that would be deposited on it's outer lens.
The focus of the camera is on the moon; thus, any debris, hair, ladedahs passing in front of the camera would be grossly blurred.
2- It is stated that the observer noticed the anomaly "orbit". There is a pattern; thus, it is highly unlikely that there is any random
interference between the observer and the Moon.
3 - There is no friction in space; consequently, aerodynamics of a space vessel are not necessary.
4 - Fuels used for propulsion
...a - A species with advanced capabilities is HIGHLY unlikely to use such a primitive propulsion system (fossil fuel); we cannot speculate on
propulsion systems
...b - Once a desired velocity is achieved in the confines of space, momentum will maintain a constant speed. "Action - Reaction, No friction so
No deceleration (reaction) "
Enjoy.
I am in the park, it is five or six pm and I am walking with my dog, and enjoying the third day of a full moon. At this moment I knew, that I
would be going tonight to the loft to take some pictures of the moon. Something I have never done before. It is the third day of a full moon and the
last one. I do not know why, but I do have a very strong feeling that, no matter the time, I will be taking pictures in the loft at the right moment.
We recently had two lunar eclipses, and I did not even think about taking pictures.

There is a huge ufo, a few kilometres in size orbiting the moon many times. Take a close look at the times between the photographs, and it is obvious,
that this object is orbiting a moon at the speed of two orbits per minute. If you are able to calculate the speed based on dates and times, please do
so.
