3. Observed solar spectrum

A high resolution spectrum of a large sunspot recorded by Brynildsen et al. (1989) with the Fourier Transform Spectrometer at the McMath telescope of NSO/NOAO at Kitt Peak, is compared with the laboratory FeH spectrum. The present umbral spectrum is from a large sunspot of diameter tex2html_wrap_inline1607 arcsec. The spot is denoted San Fernando 535. The magnetic field strength of this spot umbra is tex2html_wrap_inline1609 (Brynildsen et al. 1989). This atlas also gives the corresponding photospheric spectrum from a quiet region very close to the spot.
