Exceptional Multiple Meteor Event Recorded In Brazil

Exceptional multiple meteor event recorded over Brazil

An exceptional multiple meteor event took place over Brazil at 07:10 UTC on June 26, 2019, and was recorded by a BRAMON video station in Maranhão, Brazil. The preliminarily calculated radiant of this cluster does not seem to be associated with any known meteor shower.

At least 9 meteors were registered simultaneously in less than 1 second, all parallel to each other, BRAMON reports.

“Meteor clusters like these originate from the same meteoroid that broke apart before hits Earth, but the fragmentation usually occurs over a few hours, perhaps days, before its encounter with the terrestrial atmosphere,” BRAMON’s Marcelo Zurita noted.

BRAMON suggested several possible origins for the fragmentation that generates a cluster of meteors like this:

– It’s possible that the meteoroids originated from a recent common ejection of a comet or asteroid passing close to the Earth, may have been a low cohesive meteoroid that has been fragmented by the collision of a microparticle, or

– from a meteoroid with volatile material in its composition that has been vaporized due to the action of the Sun, dispersing the rocky fragments shortly before its encounter with the Earth.

Most of the previously reported clusters were recorded during outbursts of Leonid meteor shower in the early part of this century.

“This one appears as a very rare type of cluster recorded out of period of a great shower and its preliminarily calculated radiant does not seem to be associated with any known meteor shower,” Zurita said.
