Toby Joshua Johnston, Texas prisoner # 1377558, is serving a 35-year term of imprisonment for possession of child pornography, aggravated sexual assault of a child under fourteen years of age, and sexual performance by a child. In 2007, Johnston filed an unsuccessful 28 U.S.C. § 2254 petition challenging his convictions. In July 2015, he filed a motion for relief from judgment pursuant to Federal Rule of Civil Procedure 60(b) seeking relief from the denial of his § 2254 petition. The district court denied the motion on the ground that it was not filed within a reasonable time as required by Federal Rule of Civil Procedure 60(c)(1).

Johnston now seeks a certificate of ap-pealability (COA) to appeal the district court’s denial of his Federal Rule of Civil Procedure 60(b) motion. He also has filed motions for leave to file a corrected brief and a supplemental brief, as well as a motion to take judicial notice of adjudicative facts.

Before he can appeal the denial of his motion under Rule 60(b) of the Federal Rules of Civil Procedure, Johnston must *258 obtain a COA. See Ochoa Canales v. Quarterman, 507 F.3d 884, 888 (5th Cir. 2007). The district court did not determine whether Johnston was entitled to a COA, Because the district court has not issued a COA ruling, we assume without deciding that we lack jurisdiction over the appeal. See Rule 11(a), Rules Governing § 2254 Proceedings; Cardenas v. Thaler, 651 F.3d 442, 444 & nn.1-2 (5th Cir. 2011). Nevertheless, we decline to remand this case to the district court for a COA ruling because the appeal is frivolous, and a remand would be futile. See United States v. Alvarez, 210 F.3d 309, 310 (5th Cir. 2000).

In the alternative, even if we have jurisdiction over the appeal absent a COA ruling in the district court, we would deny a COA, To obtain a COA, Johnston must establish that reasonable jurists would debate that the district court abused its discretion in denying the Rule 60(b) motion. Hernandez v. Thaler, 630 F.3d 420, 427-28 (5th Cir. 2011); see Slack v. McDaniel, 529 U.S. 473, 484, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000). He has failed to make the required showing.

Accordingly, the appeal is DISMISSED for lack of jurisdiction, and Johnston’s motions for a COA, for leave to file a corrected brief, for leave to file a supplemental brief,- and to take judicial notice of adjudicative facts are DENIED AS MOOT.
