Roberto Gorelli points our attention at a recently published meteor related paper:

Could a Bolide Listed in the CNEOS Database have Originated from 1I/’Oumuamua?

This article has been submitted for publication by Adam Hibberd.

Abstract: The phenomenon of 1I/’Oumuamua introduced the interstellar object (ISO) class of celestial body into the astronomical lexicon, those objects with  heliocentric speeds clearly in excess of that required to parabolically escape the Solar System – and therefore of extrasolar origin. A vogue topic at this moment in time is the possibility that some ISOs may impact with Earth, where they would be observed as bolides (meteor fireballs). There is the claim for instance that a meteor listed in the NASAJPL CNEOS (Center for Near Earth Object Studies) database, CNEOS 2014-01-08 was interstellar, and additionally four further meteors from the database with interstellar origin have been proposed. This paper postulates that the origin of yet another meteor from this catalogue, CNEOS 2017-10-09 (observed over Bolivia, South America), was interstellar, as it may have been associated with ’Oumuamua. Note there is no direct velocity data for this object available, yet its observation time corresponds to the expected arrival time of an object ejected from ’Oumuamua and intersecting Earth’s orbital position.
