Explanation:
Over a thousand meteors flash through
the night in this
intriguing timelapse video.
Starting in April 2019 the individual video frames
were selected from 372 relatively clear nights of imaging
from an automated wide-field observatory in rural
New South Wales Australia.
Arranged by
local sidereal time,
a timekeeping system that uses the
positions of stars to measure Earth's rotation,
the frames follow the full annual progression
of constellations through the wide field of view
seen from 33 degrees south latitude.
They capture a
diverse array of
meteors
including
sporadic
meteors,
bright fireballs, and shower meteors (plus a
lightning
sprite),
during the period.
All frames were processed consistently and so show real variations
in the local sky conditions.
