The very luminous millisecond binary radio pulsar PSRJ0218+4232 has been detected in soft X-rays, at a luminosity of 8.4x10³²erg/s between 0.1-2.4keV. The EGRET source 2EGJ0220+4228 has a position which is consistent with that of PSRJ0218+4232. Both the X-ray source and the γ-ray source show indications for variations at the pulse period. If the γ-ray source is indeed the radio pulsar, then the energy loss in γ-rays corresponds to about 10% of the spin-down luminosity. The X-ray luminosity of PSRJ0218+4232 is high, but in line with the luminosity of PSRB1937+21 of ∼2.3x10³²erg/s.
