IT LIT up the night sky from Mindarie in Perth’s north to Meckering in the east and across the Wheatbelt — but exactly what it was is a mystery.

Social media went into overdrive last night after a “flaming object” lit up the horizon before apparently exploding and “continuing off into the clouds”.

Some posted that a “huge bang” had been heard “out Northam-York way” about the time there was a “flash in the sky”.

Richard Hannington tweeted that a “meteor or something else just shook our house a few minutes ago in York”.

The light was spotted over Ellenbrook around 7.40pm. With Monique Upson tweeting that it came through blue, went bright white before hitting the ground and exploding.

Some people rang the Perth Observatory, with one fearing it could be a plane crash, but a source said the event was more likely a meteor.
