   OPINION

PER CURIAM.

Derrick Brown, a federal inmate, appeals an order of the United States District Court for the Middle District of Pennsylvania dismissing without prejudice his petition for a writ of habeas corpus under 28 U.S.C. § 2241. For the following reasons, we will affirm.

In July 2014, Brown filed a § 2241 petition alleging that he has been subject to prolonged confinement in the Special Management Unit (SMU) at USP-Lewisburg. In particular, he claimed that his placement in the SMU deprived him of the opportunity to obtain all possible good time credits and seek a lower custody classification. He also alleged that he should have been transferred to another facility rather than have his time in the SMU extended. Finally, he asserted, that the prolonged SMU confinement aggravated his mental illness. As relief, Brown sought damages, transfer to another prison, medical and mental health evaluations, issuance of subpoenas, an evidentiary hearing, and an investigation of his claims.

The District Court held that Brown’s claims were not cognizable within a habeas corpus proceeding because he challenged only the conditions of his confinement. According to the District Court, “there is no discernible contention by Brown that his SMU placement resulted in any actual loss of good time credits or otherwise extended the length of his confinement.” Therefore, the District Court dismissed Brown’s' petition without prejudice to his right to reassert his claims in a properly filed civil rights complaint. Brown appealed.

We have jurisdiction over this appeal pursuant to 28 U.S.C. § 1291, and our review of the District Court’s dismissal of Brown’s § 2241 petition is plenary. See Cradle v. U.S. ex rel. Miner, 290 F.3d 536, 538 (3d Cir.2002) (per curiam).

We agree with the District Court that Brown’s claims were not properly brought under § 2241. Section 2241 “confers ha-beas jurisdiction to hear the petition of a federal prisoner who is challenging ... the execution of his sentence.” Woodall v. Fed. Bureau of Prisons, 432 F.3d 235, 241 (3d Cir.2005). While we have noted that “the precise meaning of ‘execution of the sentence’ is hazy,” we have made clear that a challenge under § 2241 must be to the manner in which the sentence is being “put into effect” or “carr[ied] out.” Id. at 242-43; see also Cardona v. Bledsoe, 681 F.3d 533, 537 (3d Cir.2012) (explaining that, in order for a prisoner to challenge the execution of his sentence under § 2241, he must allege that the “BOP’s conduct was somehow inconsistent with a command or recommendation in the sentencing judgment”). Brown’s allegations of prolonged placement in the SMU and the resulting consequences, including the possible loss of good time credits, concern the conditions of his confinement, not the manner in which his sentence is being carried out. See id.; Learner v. Fauver, 288 F.3d 532, 542 (3d Cir.2002) (“[W]hen the challenge is to. a condition of confine-mént such that a finding in plaintiffs favor would not alter his sentence or undo his conviction, an action under § 1983 [and not habeas corpus] is appropriate.”). Therefore, the District Court properly determined that Brown’s claims are not cognizable under § 2241, and properly dismissed the petition.

For these reasons, we will affirm the District Court’s order. 
      
       This disposition is not an opinion of the full Court and pursuant to I.O.P. 5.7 does not constitute binding precedent.
     
      
      . According to the Bureau of Prisons' Inmate Locator, Brown is currently incarcerated at at the U.S. Penitentiary ADMAX, in Florence, Colorado.
