Bolides over Southern Europe

At www.q-mag.org/anne-marie-de-grazia-my-encounter-with-a-bolide.html … she describes the coincidence of a bolide lighting up the night sky at roughly the same time as a Near Earth asteroid passed relatively close to the Earth. This she compares with the Chelyabinsk meteor of February 2013 which also coincided with a close flyby of a Near Eart Object (an even bigger asteroid passing close to the Earth). It's all a bit of a mystery. The Chelyabinsk meteor was said to be a coincidence – but do such coincidences come in pairs?
