Comments on the paper 'Do flux transfer events cause long-period micropulsations in the dayside magnetosphere?' by Gillis, Rijnbeek, Kling, Speiser and Fritz.

The conclusions of Gillis et al. [1987] that "a correlation --- [does not exist] between FTE's [flux transfer events] and Pc pulsations with periods greater than 120s" and that "there does not appear to be a correlation between midday Pc5 activity and FTE's" are not supported by the analyses and discussions presented in their paper.
