| Abstract: | Bright emission arches in the spectra of H and the Ca II (H and K lines) are identified as the spectroscopic picture of the chromospheric network as it appears near the solar limb. Analysis of the geometrical properties of these spectroscopic arches indicates that the average network is a diverging sheet with a divergence angle of  50°. This sheet extends to 2600 km and 2000 km as an opaque emission feature in H and the Ca II (H and K) lines, respectively.The National Center for Atmospheric Research is sponsored by the National Science Foundation. |
