Limb darkening observations are important for the construction and verification of solar model atmospheres. We investigate the consistency of solar limb darkening data, published for the UV wavelength region between 2000 and 3300 Å, from the comparison of ratios based either on direct limb darkening observations or on absolute irradiance (F) and disk--center intensity () measurements. There exists a discrepancy between the limb darkening data of Moe & Milone and other, direct or indirect, limb darkening observations.

Key words: Sun: atmosphere --- UV radiation
