A westward trajectory extension for the earth-grazing fireballs seen on 9 February 1913

Abstract

A unique procession of several dozen fireballs, later called cyrillids, crossed much of southern Canada on 9 February 1913. We use data from historical sightings to extend the cyrillid trajectory westward from the path examined previously. Knowledge of this trajectory enables us to identify a previously unreported sighting made near Nanoose, British Columbia. There, possibly illuminated by the setting sun, the cyrillids made a brilliant and frightening display against a sky already dark.
