Carlos Tijerina, Texas prisoner # 1349165, moves this court for authorization to proceed in forma pauperis (IFP) on appeal following the district court’s dismissal of his 42 U.S.C. § 1983 suit pursuant to 28 U.S.C. § 1915 and 28 U.S.C. § 1915A as frivolous, malicious, and for failure to state a claim upon which relief could be granted. Tijerina’s motion to proceed IFP on appeal is construed as a challenge to the district court’s certification that his appeal is not taken in good faith. See Baugh v. Taylor, 117 F.3d 197, 202 (5th Cir. 1997).

Tijerina argues that the defendants violated his rights during the course of his prosecution, direct appeal, and state post-conviction proceedings. He also argues that Judge Darnell and the prosecutor defendants are not entitled to immunity. Ti-jerina moves this court to take judicial notice of his pending 28 U.S.C. § 2254 proceedings. Tijerina does not address the propriety of the district court’s determination that his suit was untimely, nor does he address the district court’s determinations that his claims against one defendant were malicious and that his claims against the defense attorney defendants are not cognizable under § 1983. Tijerina has thus abandoned any challenges he may have had to these determinations. See Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993); Brinkmann v. Dallas County Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987).

Tijerina has not demonstrated that he will raise a nonfrivolous issue on appeal. See Howard v. King, 707 F.2d 215, 219-20 (5th Cir. 1983). Accordingly, his motion to proceed IFP is DENIED. See Baugh, 117 F.3d at 202. Tijerina’s motion for judicial notice is likewise DENIED. His appeal is DISMISSED as frivolous. See 5th Cir. R. 42.2.

The district court’s dismissal of Tijeri-na’s suit as frivolous and the dismissal of this appeal as frivolous both count as strikes for purposes of 28 U.S.C. § 1915(g). See Adepegba v. Hammons, 103 F.3d 383, 387-88 (5th Cir. 1996). Tijerina is WARNED that, if he accumulates three strikes pursuant to § 1915(g), he may not proceed IFP in any civil action or appeal filed while he is incarcerated or detained in any facility unless he “is under imminent danger of serious physical injury.” § 1915(g).
