      The INTEGRAL Public Data Archive at the ISDC opened on July 19, 2004. By agreement with ESA and the ISDC, the public data archive will be mirrored at the HEASARC, in order to facilitate ease of distribution, notably for U.S. based researchers. The HEASARC W3Browse facility will be the interface to the archive at either site. The HEASARC archive will open by September 1, 2004.
    March 2004:
      The evaluation of stage-II proposals to NASA for support of US INTEGRAL AO-2 Guest Observations was completed in March 2004. Notification letters have been issued to all proposers, and the grant administration process is underway.

      The level of US participation in the INTEGRAL Guest Observer Program remained significant. 23% of all ESA-approved AO-2 programs had US PIs and 37% US participation as PIs or Co-Is.
