To recap for the new groups. I've been making highly processed
AI-assisted movies of images taken by the TESS telescope. The
instrument orbits around the moon and Earth every 2 wks and takes
happy snaps on its YUGE array of cameras every 20s. It's on the
look-out for dimming of stars that signal "we found a planet".
My process is more concerned with finding things dimming or
brightening between the starry bits.
In the past few years we've seen a few different things that range
from "probable asteroid" to unidentified. But the frame that popped
out of the image pipe this morning is in a class by its own.
Originally we had an image of several streaks that seemed to be
approaching the camera but headed under the line of sight. Since the
telescope was nowhere near the earth at that point in 2020 there is no
real chance they are meteors entering the Earth's atm. They could be
glowing by Earth/Sun/Moonlight of course. But there is that funny knob
on the end of the streak(s). And there are several other streaks down
in the corners of the image showing it was a whole bunch of these
things going past the telescope, not just the couple in the centre of
this frame.
And now I've assembled the closes images available to the initial odd
one. A couple show nothing. 2-3 hrs before the funny shot the view
was "just a few little moving dots" (probably asteroids?). But the
image immediately prior shows several bright blobs seeming headed for a
direct hit on the camera and managing to swerve out of the way in
time.
Are these the Moon Pigeons I've heard so much about?
The image immed after (about 5m later -- the timestamp on the image is YYYYdddHHMMSS where ddd is day-of-year) shows a couple more streaks in
the background. More of the same group. (The shot after that is again
empty of anything except distant slowly moving bright dots).
So. Again. What the freak is this?
