Abstract

We report XTE and SAX observations of the X-ray pulsar RX J0146.9+612, the neutron star/Be binary system with the longest known spin period. Data obtained one month after the most recent outburst (July 1997), show that the source has returned to its normal luminosity of a few 10³4 erg/s while spin down continued at an average rate of about 5x10e-8 s/s.
