My apologies - I thought you were talking from the point of view of an
observer not the cosmonauts. As Bill Bard has said NASA certainly don't
seem to mind. I suspect that they would prefer the very final appraoch
(last 10 metres) to be in sunlight possibly. One limiting factor (and
more important I guess) may be the requirement for both vehicles to be
able to be in contact with their respective control centres throughout.
