The W30 complex consists of 7 Ultra-Compact HII regions and the SNR G8.7-0.1 at a distance of 6+/-1 kpc. The estimated age of the SNR is ~ 10,000-50,000 years and the angular size is ~ 1(deg) implying a diameter of ~ 90 pc. At the southwestern edge of the SNR is the young ( ~ 1.6times 10(4) yr) pulsar PSR 1800-21. The distance to the pulsar, based on the radio dispersion measure, is ~ 4.5 kpc. The coincidences in space, on the sky, and in age of the SNR and pulsar have led to a suggested association (Kassim and Weiler, Nature, 343, 146 (1990)) of the two. We present data from the Position Sensitive Proportional Counter (PSPC) onboard ROSAT acquired in 1992 while PSR 1800-21 was being observed. The pulsar was not detected but diffuse emission from the northern region of G8.7-0.1 was detected at a rate of ~ 0.76 c/s. The X-ray morphology and the thermal parameters of the SNR, based on spectral modeling, and a discussion of the implications which this observation have for the suggested pulsar/SNR association will be presented.
