or while in penumbra + umbra ??

I don't see why not.

The only problem is the way the laser is directed, towards the ground track. 
The spot of light from the laser on the ground at the ground track, is 
approx 70 m across.

So it wil be hard to see laser light coming directly from the laser it 
appears, unless you go to the ground track.

What do you think?
