Already at about 600,000 km from the nucleus, i.e. 12 hours before the closest approach, the Johnstone Plasma Analyser (JPA) detected the first presence of cometary ions. At a distance of 18-15,000 km, both the JPA and the Reme Plasma Analyser (RPA) reported what looked like a bow shock or a bow wave, much more distinct than had been predicted for such a weak comet. The magnetometer measurements carried out during the inbound trajectory could not confirm this finding, but reported exciting wave phenomena not seen in a natural plasma before. However, on the outbound trajectory the magnetometer saw clear indications of a shock.  2, fiche 1, Anglais, - Reme%20plasma%20analyser
