✦ Synopsis

1Univ. of Panjab (India) -2Univ. of Rajasthan (India) -aVECC (India) -4Univ. of Geneva (Switzerland) -5Kurchatov (Russia) -~JINR (Russia) -7ORNL (USA) -*Univ. of Jammu (India) -9Univ. of M/inster (Germany) -mSUBATECH (France) -llGSI (Germany) -12NIKHEF (Netherlands) -laUniv, of Lund (Sweden) -14Univ. of Tsukuba (Japan) -tSNPI (Czech Rep.) -16KVI (Netherlands) -~TINS (Poland) -ISMIT (USA) -19Bhubaneswar (India) -2°Univ. of Tennessee (USA) -aUniv of Karlsruhe (Germany) Anisotropic transverse flow has been studied with a magnetic spectrometer at midrapidity and the Plastic Ball detector at target rapidity in the WA98 experiment. Our preliminary results show the existence of directed and elliptic flow in semi-central Pb+Pb collisions. The magnitude of the directed flow is found to be significantly smaller than those observed at the AGS energies.
