Using a very high precision spectral calculation applied to theincompressible and inviscid flow with initial condition $\psi_0(x_1, x_2) =\cos x_1+\cos 2x_2$, we find that the width $\delta(t)$ of its analyticitystrip follows a $\ln(1/t)$ law at short times over eight decades. Theasymptotic equation governing the structure of spatial complex-spacesingularities at short times (Frisch, Matsumoto and Bec 2003, J.Stat.Phys. 113,761--781) is solved by a high-precision expansion method. Strong numericalevidence is obtained that singularities have infinite vorticity and lie on acomplex manifold which is constructed explicitly as an envelope of analyticitydisks.Comment: 19 pages, 14 figures, published versio
