P
Could you measure the time?
116:03:23
C
Time was - stand by.
116:03:26
P
Well, let's see, maybe we can get a colored star here.
116:03:31
C
I just got ... star.
116:03:33
P
116:03:34. Star passed - dim star passed through the airglow and did not ...
116:03:38
C
I don't see how the airglow could be used for horizon measurements.
116:03:40
P
No, definitely not. The bright band, I say "bright", just as relatively speaking for the rest of the airglow.
116:03:47
C
Now look, there's a dim star coming up right out there now, Jim.
116:03:49
P
Yes.
116:03:52
C
See it? Very dim, coming right through the airglow, following it all the way through, not occulted at all. Right through the airglow.
116:04:03
P
You can see through the bright bands, which is - -
116:04:05
C
Right through the bright bands. Right. And it's a very dim star.
116:04:07
P
I'm sure you can't use the airglow, the top airglow layer that we see as a - as a navigation mark, since it is too fuzzy. A much better one is the horizon of the earth, which is probably a bright airglow, and we just don't notice the difference of that and the end of the clouds. That is probably much better - horizon - to use than anything else.
116:04:38
C
I'm - I'm struck with the clearness of the clouds in this full moon.
116:04:41
P
Yes. A full moon makes a big difference.
116:04:44
C
You might think you're just in daytime - -
