relatively black compared to the outside. And this is true and they looked out through the window uh, there seemed to be a change. In fact, they have a photograph of this (spot) . . . . . talk about that. Uh, they are very uh, they say the astronauts have taken advantages of every possible opportunity . . . . to note something unusual. And he keeps all the copies . . . . . . . Uh, . . . . . . I think we can look a little bit to the future. I think we all would like to extend the . . . . range of vision and the way to do that is with image converters. This may be very practical. Uh, if one is dealing with uh, the idea of perhaps using a violet lens rather than a blue to get down to a region that is . . . . many more comments on. You may be getting into a region where the eye is not very sensitive or not sensitive at all, yet it is a very interesting region to do practical navigation well, there one can use the image converter and have the eye become sensitive through an image converter to uh, (the near violet). There are many observations that have made from rockets that are hard to repeat. Uh, for example, ultraviolet aurora. We're not sure this happened but uh, two of these . . . . . in a rocket and through air and it got saturated and it turns out that it probably was a very strong ultraviolet aurora over Wallops Island. And fortunately two of the (sactometors) worked and because they were . . . . to such high sensitivity but the other two were . . . . Well, uh, there was no visible counterpart of this area; there was no way of knowing it; satellites have . . . . . . astronauts might be able to look around and see . . . . . ultraviolet aurora. They saw this aurora in south Australia visually. Well, that's the beginning. Perhaps with image converters they might pick up some other aurora. . . . . . . . ultraviolet . . . . uh, is a very . . . . region; we don't know whether the picture of the aurora is going to be
