By integrating the relativistic hydrodynamic equations introduced by Taub wehave determined the exact EQuiTemporal Surfaces (EQTSs) for the Gamma-Ray Burst(GRB) afterglows. These surfaces are compared and contrasted to the onesobtained, using approximate methods, by Panaitescu & Meszaros (1998), Sari(1998), Granot et al. (1999).Comment: 4 pages, 4 figures, to appear on ApJ Let
