Abstract
A rapid scanning high resolution photoelectric spectrometer designed for the study of sunspot spectra is described. The spectrometer employs an on-line computer for signal integration, and to reject scans that are contaminated by false light due to ‘ seeing ’. The apparatus is installed at the Gornergrat, Switzerland, at a height of 3090 metres. An example of its performance is given.Keywords
