Comparison of spectra of the Kindberg and Ribbeck (2024 BX1) bolides in the range 3900–8300 Å. The Kindberg spectrum has been vertically offset by 50 units. Atoms, ions, and molecules contributing to the observed lines and bands are identified using the symbols from the legend. In some cases, two atoms contribute to one line. In other cases, one symbol is used for two or more neighboring lines of the same atom(s).
