| Abstract: | Low-noise observations have been obtained to search for a possible limb effect in the K i 769.9 nm resonance line. The observations were carried out along the north/south diameter of the solar disc. The data were individually corrected for the effects of straylight on the velocity measurements. A small, but significant limb effect is detected. The total shift in the line core from center to limb corresponds to 125 m s–1 with an uncertainty of < 30 m s–1. |
