IOTA Observations of the 2010 July 11 th Total Solar Eclipse from French Polynesia 2010 Sept. 30 Institute dAstrophysique de Paris David W. Dunham, IOTA With observations by R. Nugent, P. Maley, and C. Herold
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.
3 The IOTA observers chords relative to the predicted lunar profile
