An article will be published in 2013 with complementary observations of large professional telescopes.
This campaign involved three amateur observatories, Franck Houpert, Stephane Charbonnel and me, during five month with daily observations of FF cam. Thanks for having joining this effort.
Three professional observatories were associated, one spectroscopic in USA, UNCG observatory (http://gabalou.canalblog.com/archives/2 ... 59164.html) and two photometrics, Crimean Astrophysical
Observatory, Nauchny, Ukraine and Sternberg Astronomical Institute, Moscow, Russia. Thanks for the pros.
In parallel an amateur photometric campaign was organized with emmanuel Conseil and michel Favret showing that this system does not eclipse.
