Well Paolo, It's very difficult to determine what is going to be the exactly magnitude by the moment. We must wait for the launch and by way of the observations try to know the magnitude. In the brightness there are influce if very differnt factors like the sun position and the angle of the pannels. Saludos, Javi Zaragoza, Spain Lat: 41.64056 Long: -0.87526 Alt: 253m. Datum: WGS84 -------Mensaje original------- De: Paolo Morini Fecha: 06/06/05 14:35:00 Para: seesat-l@satobs.org Asunto: Cosmos 1 solar sail expected magnitude Hello, I have searched in the Planetary society web site, but I have not found any reference to the expected visual magnitude of Cosmos 1. I have got the idea to set up an observing point from the sailing club where my daughter go sailing with her (very) small boat, to involve both teen agers and grown ups in observing a solar sail. Also some activity from local Planetarium could be set. Of course, if we are going to get, say, a +4 magnitude, it's very hard to get more than some "groan !" from unexperienced people involved, better to observe alone in my backyard ... Anybody has some data/extimation about? Thanks a lot Greeetings from Italy Paolo Morini -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
