It left a persistent train
or smoke cloud, visible for 15 minutes after the fireball.
These include: time of appearance (UT); apparent magnitude (brightness); type (shower member, or random, 'background' sporadic); constellation in which seen; presence and duration of any persistent train
CENTRAL Trains today launched a hard-hitting campaign to crack down on persistent train
Duration was about 4 seconds, left a 4 seconds persistent train
, and disappeared in a small cloud of smoke which persisted for more than 15 minutes.
Colour yellow becoming white, duration 2 seconds, no fragmentation or persistent train
Visual observers carried out watches by the Meteor Section's standard method, (9) recording type, time of appearance, magnitude, presence and duration of any persistent train
, and other parameters for individual meteors.
They are typically fast and bright, and they occasionally leave persistent trains
The Perseids have a large number of bright meteors, many of which leave persistent trains
," says Dr John Mason of the British Astronomical Association, "and people like to watch it on a warm summer's evening.
These are swift meteors that produce a high percentage of persistent trains
, but few fireballs," the description on the American Meteor Society calendar reads.
The shower has a tendency to produce bright meteors, often with persistent trains
So any shower members seen will be earthgrazers that skim far across the top of the atmosphere nearly horizontally and leave long, colorful, persistent trains
(as observed in 1986 and 1994).
Jane Houston Jones of the National Aeronautics and Space Administration (NASA) declared in a blog post that the Lyrids are known to producing bright meteors where several have persistent trains
