According to the photos taken from Finland, the sail should be still off axis of at least 45 degrees. More details are available on the following web page, where I uploaded also a couple of screenshots depicting the flare ground tracks with the same sail orientation (if it takes sense...) http://digilander.libero.it/SATrack/NanosailFlares.html Best regards, Simone >----Messaggio originale---- >Da: direland@drdale.com >Data: 1-feb-2011 23.10 >A: "SeeSat-L"<SeeSat-L@satobs.org> >Ogg: RE: Nanosail questions > >It doesn't appear to be flat.
