According to NASA -

Earth is entering a field of debris.

August is the month for Perseid Meteor showers.

PERSEID METEOR SHOWER:
Earth is entering a stream of debris from Comet Swift-Tuttle, source of the annual Perseid meteor shower. International observers are now reporting more than a dozen Perseids per hour, a number that will increase as the shower reaches its peak on August 12-13. Full moonlight will reduce visibility on peak night, but not enough to completely spoil the show--especially when the ISS is scheduled to make an appearance among the meteors
