I agree there could be a faint visible light because of plasma. Faint. incomparable to sunlight.
But, if this visible light it is there in the great amount like you suggest, then why astronauts didn't see the tether until orbital sunrise ocurred?
ANSWER: because this light from the plasma is very faint. Much fainter than the light reflected from the sun. Argument: imediately after the tether break, when already was fully deployed, we see in video the tether, a simple wire, and we see it because is sunlit, not because some faint plasma brightness.

This really has been discussed thoroughly before, please do your homework before demanding a one-on-one remedial tutorial.
The camera effect of blooming, where bright pixels leak over onto nearby ones, is a bane of the simple cameras in use in the payload bay in those years.
You can tell the thickness is an artifact when, even as the camera is zoomed in and out, and the length expands and contracts, the thickness remains the same -- an artifact, not a real visual characteristic.
The tether did not look that thick to the naked eye, either -- another indication the thickness is a camera artifact, not a genuine visual feature.

Ground observers did not see the tether in Earth's shadow, but only as it was emerging from that shadow and afterwards.
I don't see as much blooming in that video but remember the shuttle camera used a vacuum tube image sensor which is unusual, most cameras don't use vacuum tube image sensors but instead use some other technology like CCD image sensors.

is there also camera blooming in this video ?

does camera C prove there was no plasma field associated with the tether ?
Nope it does not

there you go posting lies again !
quote me where i say i do not want to see a better copy than secretnasaman's video
if you can't then admit your making up lies and posting them
"no offense to DOF or secretnasaman but the video in the condition we have is not worthy of scientific analysis in that perspective. motion tracking is even questionable so your argument that DOF has proven anything is ridiculous. you already know what i said about the ufo hunters video. "
Are you afraid from what we can discover?
Thanks for that, maybe I did make a mistake but if so it was a misunderstanding.
Regarding the distance, and blooming, I'm looking at the length to width ratio, so in comparing 2 different videos, if you make the length comparable in each of them (such as by taking screenshots of each and putting them side by side and stretching one until the length is the same), that should normalize the effects of distance and zoom, etc for the most part. Then I'd say the video that shows a wider width demonstrated more blooming.

My logic is terminated on this contradictory statements. Shutting down.

No Mcrom901, YOU are wrong on that.
As Arbitrageur explained just before...
As myself or Jim Oberg explained a few times before...
As others explained, i didn't remember now...
As simple attention watching the movie can verify this...
I asked pretty much the same question on 16 Oct. '98. How could the
2.4 to 2.6 mm tether could be seen at 200 km without magnification? My
answer covered about fifteen or so posts, but none were satisfatory. I then
did the math and found that the tether, 19 km long, would represent about
50 sq. meters or about 540 sq. ft. if it was run back and forth to form a
solid partition. Still, the tether was very slim and it was a long way away,
it didn't seem possible that it could be seen at 200 km without strong
magnification.
Then on 4 Nov. '99, NASA posted some information about TiPS, the
RM400 conductive coating had "tremendous emissions of secondary
electrons," from "solar particle bombardment or ultraviolet light or
both." This would act just like reflected light, that is, when the tether and
satellites entered the sunlight and could become visible, the tether would
be bombarded with particles and ultraviolet light at the same time, so it
may not be posssible for amature observers to determine if the tether was
seen because of reflected sunlight or electron emissions surrounding the
tether in a visible sheath from the electrons.
My question is, would the the electron sheath produce a visible glow
that could account for a 2.6 mm tether being seen from great distances?
Several persons have noticed that the tether has become dimmer with time.
Read the NASA posting at:
science.nasa.gov...
The information you want to read is IN THE LAST THREE PARAGRAPHS.
so it may not be posssible for amature observers to determine if the tether was
seen because of reflected sunlight or electron emissions surrounding the
tether in a visible sheath from the electrons.
