Description

On 08.01.2024 night three of our meteor cameras have captured quite a bright fireball. One of them has a diffraction grating, so we've got a fireball's spectrum. A set of lines typical for a chondritic meteorite is visible in the spectrum. All lines represent neutral atoms, lines of ionized elements are absent. This is associated with the low velocity of the meteoroid (Vg=12.4 km/s). The ratio of Mg-Fe-Na lines shows approximately equal intensities of these elements, but with some excess of iron. It is precisely due to the bright lines of iron (as well as magnesium) in the green region of the spectrum that this bolide has a bright green hue in the color image. The spectrum revealed lines of the following chemical elements: iron, magnesium, sodium, chromium, calcium, silicon, potassium, manganese, nickel, titanium, oxygen ,and nitrogen.
