  "abstract": "We present 12 low-resolution meteor spectra recorded at four stations of the Skytinel network in Poland, focusing on consistent reduction and comparison of Fe, Mg, and Na emission features. Spectra spanning approximately 350--850 nm were extracted, background-subtracted, and wavelength-calibrated using IRAF. Corrections accounted for the wavelength-dependent quantum efficiencies of Sony IMX249 and IMX273 detectors and atmospheric attenuation as a function of observing geometry. The corrected spectra were decomposed into Fe, Mg, and Na components using selected atomic transitions, temperature-dependent emissivities, and pseudo-Voigt line profiles. Integrated Fe~I-15, Mg~I-2, and Na~I-1 intensities were compared in a ternary diagram. Most spectra overlap with or lie near the normal-meteor distribution in reference samples, while some extend toward Fe-rich or Na-rich regions. The most Fe-dominated event assigns approximately 81\\% of the summed emission to Fe~I-15. These ratios characterize relative emission, not elemental abundances or bulk composition. Combined with trajectory and photometric data, spectral classification may help constrain plausible material properties in dark-flight models and refine predicted meteorite search areas.",
