The soft x-ray background observed from Earth contains contributions not only from outside the solar system such as the local bubble but contributions from within the solar system including from the interplanetary medium and from the terrestrial geocorona and magnetosheath. Great effort was spent on removing non- cosmic contamination from data collected during the ROSAT all-sky survey. Some of the contamination, however, was due to X-ray emission from solar wind charge exchange with interstellar and geocoronal neutrals. The time varying component of this contamination was removed, but the steady state component of this X-ray emission was not. We will present all-sky maps of the soft X-ray emission with the heliospheric component removed, which will allow a re-interpretation of the nature of the local interstellar bubble. We have calculated this steady statement component for and will discuss its contribution to the ¼ and ¾ keV all- sky survey maps.
