Abstract We have obtained accurate center-to-limb photoelectric spectra of the CH (0, 0) C-X bandhead region λ3143–3148 Å at Kitt Peak National Observatory. From these spectra and a detailed analysis of the formation of the CH (0, 0) spectrum we demonstrate that the best-fit upper photospheric model derived from our previous analyses of CN (0, 0) and CN (1, 1) spectra adequately explains the CH C-X observations. In addition we derive a solar carbon abundance of ±0.20 compared to the HSRA value of log Ac = 8.55. This confirms our previous CN analyses which demonstrated that if the HSRA nitrogen abundance of log AN = 7.93 ± 0.10 is assumed, then log Ac = 8.20 ± 0.10. We also specify the regions of formation for the CH(0, 0) λ3143.47 Å band-head at disc center and limb.
