Simultaneous observations of high resolution spectra of CaII H, K, lambda 8542 and kambda 8498 have been made over a sunspot umbra (SPO 5007) by means of Sacramento Peak Observatory's HIRKHAD program with the Echelle spectrograph at the Vacuum Tower Telescope. The observed spectra scanned by SPO's fast microphotometer have been reduced for later theoretical interpretations. The reduced profiles, sampled over a region which is thought to be coolest over the spot, are presented in units of absolute intensity. The core intensity ratios of I(K3)/I(H3) and I(lambda8498)/I(lambda8542) are found to be 1.3 and 1.14, respectively.
