PER CURIAM.

       Jackson Quintero Figueroa appeals the district court’s1 denial of his 28 U.S.C.
§ 2241 motion challenging the Bureau of Prisons assignment of his Residential
Reentry Center placement date. We dismiss the appeal as moot, because Figueroa was
released from custody on April 6, 2007. See Calderon v. Moore, 518 U.S. 149, 150
(1996) (per curiam) (when event occurs during pendency of appeal that renders it


      1
        The Honorable James M. Moody, United States District Judge for the Eastern
District of Arkansas, adopting the report and recommendations of the Honorable John
F. Forster, Jr., United States Magistrate Judge for the Eastern District of Arkansas.
impossible for court--if it should decide case in appellant’s favor--to grant effective
relief, court will dismiss appeal as moot).
