MEMORANDUM **

Donald L. and Karen A. Simons appeal from the district court’s order dismissing *635 their appeal from the bankruptcy court’s summary judgment against them in an adversary proceeding. We have jurisdiction pursuant to 28 U.S.C. § 158(d). We review for an abuse of discretion the dismissal of an appeal for failure to prosecute, Nat’l Bank of Long Beach v. Donovan (In re Donovan), 871 F.2d 807, 808 (9th Cir. 1989), and we reverse and remand.

The district court dismissed sua sponte after the Simonses failed to timely file documents in support of their appeal. However, the Simonses had requested a short extension to file their opening brief, the court failed to warn of dismissal or to consider less drastic sanctions, and there was no showing of prejudice to the appel-lee. Thus, we reverse and remand. See id. at 808-09 (concluding that dismissal of appeal was an abuse of discretion where Bankruptcy Appellate Panel failed to consider alternative sanctions); Moneymaker v. CoBen (In re Eisen), 31 F.3d 1447, 1451 (9th Cir. 1994) (explaining five factors courts must consider before dismissal, including prejudice to opposing party and alternative sanctions, and noting that in sua sponte dismissals “there is a closer focus on the failure to consider less drastic alternatives and the lack of warning of imminent dismissal” (internal quotation marks and citation omitted)).

REVERSED and REMANDED.
