They Filled A Space In The Sky Extending From Due
East 30 Degrees To North And South.
In an amplitude of 60 degrees
the meteors were seen to rise above the horizon at east-north-east
and at east, to describe arcs more or less extended, and to fall
towards the south, after having followed the direction of the
meridian.
Some of them attained a height of 40 degrees, and all
exceeded 25 or 30 degrees. There was very little wind in the low
regions of the atmosphere, and that little blew from the east. No
trace of clouds was to be seen. M. Bonpland states that, from the
first appearance of the phenomenon, there was not in the firmament
a space equal in extent to three diameters of the moon, which was
not filled every instant with bolides and falling stars. The first
were fewer in number, but as they were of different sizes, it was
impossible to fix the limit between these two classes of phenomena.
All these meteors left luminous traces from five to ten degrees in
length, as often happens in the equinoctial regions. The
phosphorescence of these traces, or luminous bands, lasted seven or
eight seconds. Many of the falling stars had a very distinct
nucleus, as large as the disk of Jupiter, from which darted sparks
of vivid light. The bolides seem to burst as by explosion; but the
largest, those from 1 to 1 degree 15 minutes in diameter,
disappeared without scintillation, leaving behind them
phosphorescent bands (trabes) exceeding in breadth fifteen or
twenty minutes.
