The 805 second X-ray pulsar H2252-035It is shown that the X-ray flux from the 3.6 hr binary system H2252-035 is modulated at a period of 805 sec, and that its spectrum is consistent with either (1) a 1.4 photon index power law, or (2) a greater-than-20-keV thermal model. A 560 + or - 350 eV equivalent-width iron line at about 6.7 keV is noted, and the possibility that the H2252-035 system contains a slowly rotating neutron star is discussed.
