Before COLLOTON, BRIGHT and GRUENDER, Circuit Judges.
                        ________________

PER CURIAM.

       Nicholas Bonahoom pled guilty to one count of possession of child
pornography in violation of 18 U.S.C. § 2252(a)(4)(B) and a related count of criminal
forfeiture. The district court1 sentenced him to 37 months’ imprisonment and three
years of supervised release. Eight days after entry of judgment, Bonahoom attempted
to withdraw his guilty plea pursuant to Fed. R. Crim. P. 11(e), arguing that he suffers
from several mental impairments and that he was not competent to plead guilty. Two

      1
      The Honorable Richard G. Kopf, United States District Judge for the District
of Nebraska.
days later, while his motion to withdraw his plea was pending, Bonahoom filed a
notice of appeal identifying as issues on appeal both the reasonableness of his
sentence and his motion to withdraw his guilty plea. The district court denied
Bonahoom’s motion to withdraw his plea four days after he filed his notice of appeal.
Bonahoom did not file another notice of appeal after the district court denied his
motion.

       As a preliminary matter, we have an independent obligation to examine our own
jurisdiction. United States v. Hays, 515 U.S. 737, 742 (1995). “Without jurisdiction
the court cannot proceed at all in any cause; it may not assume jurisdiction for the
purpose of deciding the merits of the case.” Sinochem Int’l Co. v. Malaysia Int’l
Shipping Corp., --- U.S. ---, 127 S. Ct. 1184, 1191 (2007) (internal quotation omitted).
 Because there is an indication that we may lack jurisdiction over some aspects of this
appeal, we raise the issue sua sponte even though the parties have not raised the issue.
United States v. Duke, 50 F.3d 571, 574 (8th Cir. 1995).

       We conclude that we are without jurisdiction to address the issue of the district
court’s denial of Bonahoom’s motion to withdraw his guilty plea. “In a criminal case,
a defendant’s notice of appeal must be filed in the district court within 10 days after
the later of . . . the entry of either the judgment or the order being appealed.” Fed. R.
App. P. 4(b)(1)(A) (emphasis added). “A timely notice of appeal is mandatory and
jurisdictional.” United States v. Austin, 217 F.3d 595, 597 (8th Cir. 2000).
Bonahoom’s notice of appeal preceded the district court’s order denying his motion
to withdraw his guilty plea by four days. Bonahoom’s premature notice of appeal of
that order does not fall within the exception found in Rule 4(b)(2) because the district
court had not announced its decision on the plea withdrawal issue prior to
Bonahoom’s filing of his notice of appeal. Likewise, Rule 4(b)(3) does not save
Bonahoom’s premature notice of appeal of his motion to withdraw his guilty plea
because the motion was not one for acquittal under Fed. R. Crim. P. 29, new trial
under Fed. R. Crim. P. 33 or arrest of judgment under Fed. R. Crim. P. 34. Because

                                          -2-
Bonahoom failed to file a notice of appeal within ten days after the district court
denied his motion to withdraw his guilty plea, “the order being appealed,” we are
without jurisdiction to address that issue. See United States v. Vasquez, 121 Fed.
Appx. 17, 18 (5th Cir. 2004) (unpublished per curiam) (holding on similar facts that
the court of appeals lacked jurisdiction and also noting that the defendant’s post-
sentencing motion to withdraw his guilty plea “was unauthorized and without
jurisdictional basis” in district court because Fed. R. Crim. P. 11(e) only allows a
guilty plea to be set aside on direct appeal or collateral attack after sentencing).

       Bonahoom’s notice of appeal is effective with respect to his challenge to the
reasonableness of his sentence, as he filed his notice of appeal within ten days after
entry of judgment. Bonahoom argues that the district court erred by failing to
consider his purported mental impairments at sentencing and that his sentence is
otherwise excessive. With respect to the district court’s failure to consider
Bonahoom’s mental impairments at sentencing, Bonahoom admits that the issue of his
mental impairments was not raised before the district court at sentencing. Thus, the
issue has not been preserved. Ordinarily, where a party has forfeited an issue through
a failure to preserve it, we review the district court’s actions for plain error. See Fed.
R. Crim. P. 52(b); United States v. Mooney, 425 F.3d 1093, 1103 (8th Cir. 2005) (en
banc). The first requirement of plain error review “is that there indeed be an ‘error.’”
United States v. Olano, 507 U.S. 725, 732 (1993). “If a legal rule was violated during
the district court proceedings, and if the defendant did not waive the rule, then there
has been an ‘error’ within the meaning of Rule 52(b) despite the absence of a timely
objection.” Id. at 733-34. Here, Bonahoom does not identify any legal rule violated
by the district court at sentencing, nor can we. As Bonahoom admits that he presented
no evidence of his purported mental impairments to the district court at or before the
sentencing hearing, the district court certainly did not violate a legal rule in failing to
consider such evidence. Consequently, we find no error, much less plain error, in the
district court’s failure to consider Bonahoom’s purported mental impairments at the
sentencing hearing.

                                           -3-
       Turning to the reasonableness of Bonahoom’s sentence, Bonahoom argues that
the district court failed to consider all of the 18 U.S.C. § 3553(a) factors at sentencing
and that his sentence is consequently unreasonable. We disagree. We review the
reasonableness of a sentence for abuse of discretion. United States v. Gnavi, 474 F.3d
532, 537 (8th Cir. 2007). “A sentencing court abuses its discretion if it fails to
consider a relevant factor that should have received significant weight, gives
significant weight to an improper or irrelevant factor, or considers only the
appropriate factors but commits a clear error of judgment in weighing those factors.”
United States v. Long Soldier, 431 F.3d 1120, 1123 (8th Cir. 2005). Further, a district
court need not “categorically rehearse” each of the § 3553(a) factors as long as it is
clear that the court considered them. Gnavi, 474 F.3d at 538 (quoting United States
v. Dieken, 432 F.3d 906, 909 (8th Cir. 2006)). The district court sentenced Bonahoom
at the bottom of the undisputed advisory guidelines range of 37 to 46 months’
imprisonment. In deciding that a downward variance was not warranted, the district
court noted that there was no reason “for deviating from the guidelines here under
3553(a).” The record does not reflect that the district court failed to consider a
relevant factor that should have received significant weight, or that it gave significant
weight to an improper or irrelevant factor or that it committed a clear error of
judgment in weighing the appropriate factors. As a result, we hold that the district
court did not abuse its discretion in sentencing Bonahoom and that his resulting
sentence was not unreasonable.

      In light of the foregoing, we affirm Bonahoom’s sentence.
