Noctilucent clouds 1997-1999

31 years of observing NLC has proved that July and August are the most weary months in my all observing. We have pretty many clear nights and they all have to be followed from sunset to at least 2am and in case of display 'til morning. And after a few hours' sleep a full day is to bear; this continuing for 6 weeks really wears out.
