Narrative:

Descending through approximately 15000 ft; noticed a crack on the side window; captain's side. No progressing was observed; air pressurization showed normal. It was sunday night (not much traffic); so I did not declare an emergency since we were pretty much vectored toward the airport with continued descent to 3000 ft for visual approach. Called maintenance on the ground after landing.
