    Jesus RODRIGUEZ-LEON, Appellant v. WARDEN ALLENWOOD FCI.
    No. 14-3525.
    United States Court of Appeals, Third Circuit.
    Submitted for Possible Dismissal Pursuant to 28 U.S.C. § 1915(e)(2)(B), Summary Action Pursuant to Third Circuit LAR 27.4 and I.O.P. 10.6 March 7, 2015.
    Opinion filed: May 12, 2015.
    Jesus Rodriguez-Leon, White Deer, PA, pro se.
    Michael J. Butler, Esq., Mark E. Morrison, Esq., Office of United States Attorney, Harrisburg, PA, Defendant-Appellee.
    Before: FISHER, SHWARTZ and GREENBERG, Circuit Judges.
   OPINION

PER CURIAM.

Jesus Rodriguez-Leon appeals the District Court’s order denying his petition filed pursuant to 28 U.S.C. § 2241. For the reasons below, we will dismiss the appeal as moot.

In 2011, Rodriguez-Leon was sentenced to 46 months in prison after being convicted of illegal reentry of a removed alien in violation of 8 U.S.C. § 1326. In 2013, he filed a § 2241 petition seeking credit for time spent in custody prior to sentencing. The District Court denied the petition, and Rodriguez-Leon filed a notice of appeal. According to the Inmate Locator on the Bureau of Prisons website, Rodriguez-Leon was released on February 18, 2015. Because it appeared that Rodriguez had served his sentence, the parties were asked to address whether the appeal was moot. Appellee has filed a response, but Rodriguez-Leon has not.

Pursuant to Article III of the Constitution, a federal court may adjudicate only ongoing controversies or cases. Burkey v. Marberry, 556 F.3d 142, 147 (3d Cir.2009). Rodriguez-Leon sought relief which would result in his earlier release from prison, and he has now been released from prison. There is no effective relief that we could' grant him. See In re Cantwell, 639 F.2d 1050, 1053 (3d Cir.1981) (“[A]n appeal will be dismissed as moot when events occur during the pendency of the appeal which prevent the appellate court from granting any effective relief.”). Rodriguez-Leon has not argued that there are any collateral consequences caused by the denial of his sentencing credit. See Burkey, 556 F.3d at 148 (when a prisoner challenges a sentence that has been served, the appeal is moot unless he can show collateral consequences.)

Accordingly, we will dismiss the appeal as moot. 
      
       This disposition is not an opinion of the full Court and pursuant to I.O.P. 5.7 does not constitute binding precedent.
     
      
      . Appellee confirms that Rodriguez-Leon has , been released.
     
      
      . Rodriguez-Leon did not provide the Clerk with an updated address, and the Clerk’s order requesting responses on mootness was returned with the notation "attempted not known unable to forward.”
