The ROMAP (Rosetta Lander Magnetometer and Plasma Monitor) suite of sensors onboard the Rosetta lander Philae consists of a fluxgate magnetometer and plasma ion and electron sensors. ROMAP will measure for the first time the magnetic field as well as electron and ion distributions on a cometary surface.
 First magnetic field measurements during the Philae descent and plasma investigations during the first science sequence on the cometary surfce will be presented together with concurrent magnetic field measurements of the Rosetta orbiter. Furthermore, we shall discuss the measurement operation strategy for the long term sequence, for observing the evolution of the plasma environment by measurements with both plasma packages, ROMAP on the surface and RPC onboard the Rosetta Orbiter.
