Circular orbits around the moon are unstable !
november 2011 - email response to me, from Mr. Anthony Charles Cook - BAA/ALPO Transient Lunar Phenomena Coordinator, regarding an older record I made with these objects
"As the objects appear much more stationary with respect to the
camera (i.e. they don't move much compared to the Moon) these
could be specks of dirt either on the camera
window or in a filter or eyepiece coating. If so then they should
appear at the same x and y coordinate on the TV screen.
Could you possibly provide me with details UT of when you took this video
and where the Moon was relative to your local horizon,
including obstructions such as trees and buildings etc
You can see the Moon shimmering away (random motions and
distortions) in our atmosphere. This is perfectly normal behavior
for anything outside or high up in our the Earth's atmosphere.
The objects do not exhibit so much of this wobbliness at
all, so therefore must lie quite close to the CCD camera. There is
a diffraction ring around them on the bright side of the Moon
which again suggests that they are slightly out of focus
compared to the sharper image of the Moon. So if they are
not specks of dirt on the CCD camera/optics, then they must be
in our atmosphere.
I've got hundreds of hours of video of the Moon
and quite often get birds, planes, satellites, meteors,
aircraft, helicopters, floating seeds, and even the ISS
flying past the Moon in the line of site, so its quite
a common occurrence.
Sorry to disappoint you. BTW a quick check on the
apparent speed, if they were at the Moon's distance,
would reveal that they are obviously not in orbit,
and very untypical of any asteroidal or cometry objects
in the solar system. So much be much closer.
Please keep up the good astro-imaging effort that you are doing
and let me know the UT time and other details associated with your video"
