Position of Rosetta in the Sky

The current position of Rosetta is computed using high quality data sets provided by the JPL Horizons ephemeris service (see acknowledgements). It is important to be aware that for objects like comets there might be large discrepancies between the predicted magnitude and the real one. This happens because comets magnitude is highly influenced by physical phenomena which can be hardly modelled and calculated in advance.
