I didn't see a reply on the magnitude question. One of my earliest space notes states that 1 m2 cross-section of a white sphere is +6.4 at 1000 km full-phase. Assuming a golf ball is 25 times smaller in diameter makes that +13.5 roughly. There is a trade-off between the range and the phase of a satellite pass, which I don't care to search for (I believe I posted it to SeeSat-L), or compute again. Assuming the "best" range is 400 km, I would get +11.5 /Björn ----- Original Message ----- > > Anyone on the list care to estimate what the visual magnitude of a > golf ball would be if in a parallel orbit with the ISS?
