MEMORANDUM **

Earnestine Thomas appeals her seventy-two month and one day sentence imposed after her guilty-plea conviction for armed bank robbery, in violation of 18 UiS.C. § 2113(a) & (d), and unlawful possession of a firearm 'in connection with a crime of violence, in violation of 18 U.S.C. § 924(c)(1). We have jurisdiction pursuant to 28 U.S.C. § 1291, and affirm.

*563Thomas contends the district court erred by failing to exercise its discretion to depart downward with respect to the sixty-month consecutive sentence imposed for violating section 924(e)(1). A district court’s discretionary decision not to depart downward from the sentencing guidelines is not reviewable upon appeal. See United States v. Lipman, 133 F.3d 726, 729 (9th Cir. 1998). A denial of downward departure, however, based upon the district court’s belief it lacked the authority to depart, is reviewed de novo. See United States v. Tucker, 133 F.3d 1208, 1214 (9th Cir. 1998).

Thomas’ contention is without merit. The district court correctly determined it lacked the authority to depart downward from the mandatory minimum sentence imposed under section 924(e)(1). See Melendez v. United States, 518 U.S. 120, 126-30, 116 S.Ct. 2057, 135 L.Ed.2d 427 (1996) (noting no jurisdiction in the absence of an 18 U.S.C. § 3553(e) motion); United States v. Riewe, 165 F.3d 727, 728-29 (9th Cir. 1999) (per curiam). Moreover, there is no evidence the government intended to make a section 3553(e) motion. See Melendez, 518 U.S. at 125-27.

AFFIRMED.
