We report on preliminary results of simultaneous eROSITA and XMM-Newton observations of the isolated neutron star PSR B0656$+$14. Data were obtained for almost 100 ks with eROSITA and 70 ks with XMM-Newton under excellent space weather conditions. The target was chosen to investigate a weak absorption feature between 0.5 and 0.6 keV that was tentatively identified in previous deep XMM-Newton observations, to exploit the improved spectral resolution provided by eROSITA. The pulsar is also used to determine the timing accuracy of the eROSITA cameras in reference to the external XMM-Newton signal. Science opportunities offered by this ultra-deep pointed observation some 8 degrees above the galactic plane are also briefly described.
