| Abstract: | New observations of the Caii]  7323 Fraunhofer line are reported. The blending H2O line was weak at the time of observation. Accurate estimates of the centre-limb variation of the equivalent width of the Caii] transition are obtained and shown to be consistent with the calcium abundance log N(Ca) = 6.33. |
