โœฆ Synopsis

We have obtained accurate center-to-limb photoelectric spectra of the CH (0, 0)C-X bandhead region 23143-3148 ~ 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, l) spectra adequately explains the CH C-X observations. In addition we derive a solar carbon abundance of logAc = 8.30 โ€ข โ€ข compared to the HSRA value of logAc = 8.55. This confirms our previous CN analyses which demonstrated that if the HSRA nitrogen abundance of logA.v --7.93 ~ 0. I0 is assumed, then logAc = 8.20 :t: 0.10. We also specify the regions of formation for the CH(0, 0) 23143.47 ,~ bandhead at disc center and limb.

Spectroheliograms taken in the CN(0, 0) violet band near 23883 A, show very small scale network and cell structures with high contrast. The bandhead itself, which is a broad feature due to overlap of several CN lines, allows the diagnostic simplicity of a continuum since motions, magnetic fields, an

Electronic waste, in the form of printed circuit boards (PCBs) or printed wiring boards (PWBs), represents a significant and growing fraction of the waste generated in many communities. It is necessary to identify schemes to manage and dispose this waste in an environmentally safe manner. The presen
