We employ data from two spacecraft, at the dawn flank of the magnetopause, to investigate fluctuations in the thickness of the low-latitude boundary layer (LLBL). We show the LLBL is considerably thinner shortly after the detection of a flux transfer event than it was during the event. These data are shown to be consistent with the theory of transient increases in the open LLBL thickness caused by a pulse of enhanced reconnection at the magnetopause.
