Abstract
The heat capacity of niobium at constant magnetic induction has been measured in the immediate neighborhood of ${T}_{c}(B)$ with millikelvin temperature resolution. An enhanced heat capacity attributable to fluctuations is observed both above and below ${T}_{c}(B)$. The temperature dependence throughout the transition region can be described over a wide temperature range by a universal curve with a temperature scale uniquely determined by measured thermodynamic parameters.
