If you're looking over at the daylight side, it looks l i ke the light tl..:ie , goes up probably three times as high as the air glow does. What do you think about that? Let me go into my impressions of the air glow in the evening. I saw the same thing you did, of course , and it looked like to me that the dark part was roughly t wo or three times as thick as the lighter air glow layer below it. We were both impressed with the phenomenon of the apparent rise in the air glow as you go from the daylight to the dark, and as soon as you get out in full daylight, the earth 's layer is all gone. But as you transition between the daylight and the dark, you see the layer start out and narrow down to what you see as you get into the dark side as the air glow layer . And when you initially get into the dark area, the air glow seems to disappear for a moment, and then the air glow layer pops out when you get into full dark, , very clearly.
