225 Pa. Code § 201 : — RULES OF EVIDENCEJUDICIAL NOTICE — Judicial Notice of Adjudicative Facts

(a) Scope. This rule governs judicial notice of an adjudicative fact only, not a legislative fact.
(b) Kinds of Facts That May Be Judicially Noticed. The court may judicially notice a fact that is not subject to reasonable dispute because it:
(1) is generally known within the trial court's territorial jurisdiction; or
(2) can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.
(c) Taking Notice. The court:
(1) may take judicial notice on its own; or
(2) must take judicial notice if a party requests it and the court is supplied with the necessary information.
(d) Timing. The court may take judicial notice at any stage of the proceeding.
(e) Opportunity to Be Heard. On timely request, a party is entitled to be heard on the propriety of taking judicial notice and the nature of the fact to be noticed. If the court takes judicial notice before notifying a party, the party, on request, is still entitled to be heard.
(f) Instructing the Jury. The court must instruct the jury that it may, but is not required to, accept as conclusive any fact judicially noticed.
