A bright meteor appeared in the morning of August 13th, 2019.
The real time video of the meteor shows the typical green train of a Perseid, which
is also visible to the naked eye for the brighter meteors. The Perseids are quite fast with about
60 km/s. This is sufficient to excite atmospheric oxygen at heights of about 100 km and emit green
light at a wavelength of 558 nm (Borovicka, 2006).
