AB  - An efficient way to study the QCD phase diagram at small finite density is to extrapolate thermodynamicalobservables from imaginary chemical potential. The phase diagram features acrossover line starting from the transition temperature already determined at zero chemical potential.In this talk we focus on the curvature of this line at mu = 0. We present the extrapolation ofthe crossover temperature based on three observables at several lattice spacings. The simulationswere performed at zero and at moderate values of the imaginary chemical potential, always in thestrangeness neutral point. We used the Symanzik-improved gauge action with four times stoutsmeared staggered fermions.
