I too have witnessed STRONG NLC (up to 40 degrees altitude) at the same time as a weak auroral display(although magnetically southern folk on this list would say it was a nice auroral display) . I did not notice the NLC become weaker as a result of the auroral activity. I have read that some people have seen aurora and NLC fade and brighten in opposite phase, though I have a hard time believing that considering my observation. However, one observation does not make a theory :).
