Rosetta's Earth fly-by on 4 March, ESA's closest ever at just 1900 kilometres.
If you've got a decent amateur telescope and digital imaging equipment, you can probably take some impressive photos of Rosetta—weather permitting—as the craft speeds by Earth.
After sunset in Europe on Friday, 4 March, the spacecraft will appear to travel from south east to south west, moving from the constellation Sextans towards the setting Sun, crossing the complete sky. Rosetta will be visible at an approximative angle of 30 degrees over the horizon. It will move faster as it heads west, disappearing below the horizon shortly after 23:00 CET. As seen from Europe, it will only reach a magnitude of about +8 or +9 on the brightness scale used by astronomers; this is dimmer than a typical faint star and not readily apparent to the eye.CET = Central European Time
