Abstract
Using Greenwich sunspot data for 120 years it was recently observed that activity regions on the Sun's surface tend to lie along smoothly changing longitude strips 180° apart from each other. However, numerical experiments with random input data show that most, if not all, of the observed longitude discrimination can be an artifact of the analysis method.
