On 4 May 2014 around 4:17pm (EDT) a daylight bolide occurred near Ontario.〔〔 The meteoroid was estimated to be roughly in diameter.〔 The air burst was estimated to be equivalent to approximately 10–20 tons of TNT.〔 The meteor was first seen in Peterborough and traveled on a southwest-to-northeast trajectory.〔〔 A meteor of this size impacts Earth about twice a week.〔 The meteor was large enough that it may have generated meteorites.〔 A strewn field has not yet been located but would be downstream after dark flight. Weather radar returns suggest that the meteorite(s) may have landed near Codrington.〔(Marc Fries (Galactic Analytics LLC) on Facebook )〕〔((meteorobs) Daylight fireball over Canada and N.E.
