Claud Gaines appeals the district court’s 1 adverse grant of summary judgment in his pro se employment-discrimination action. The district court entered judgment against him on July 16, 2015. His notice of appeal was filed on August 24, 2015, more, than 30 days later. See Fed. R.App. P. 4(a)(1)(A) (30 days to appeal in civil case), 26(a) (computing time). This court therefore lacks jurisdiction over this untimely appeal. See Dieser v. Cont’l Cas. Co., 440, F.3d 920, 923 (8th Cir. 2006) (requirement of timely NOA is mandatory and jurisdictional; federal court will raise jurisdiction issues sua sponte). Accordingly, we dismiss the appeal.
