2 2 Path of the July 11 th Total Solar Eclipse across French Polynesia They were not able to arrange observations near the path limits, as for most past eclipses, but since we knew more accurate Kaguya profile data are available, they observed from two islands at different distances from the central line and on opposite sides of it.
