A bright meteor appeared in the morning twilight of August 12th, 2018. And if you watch on the right hand side, a faint one is also visible at the same time. Astronomers are stowing away their equipment after a night of observing. 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).
