    Azimuthal distributions of both Eta and ăo mesons emitted at midrapidity are studied in collisions of 1.9 A GeV 58Ni+58Ni and 2 A GeV 40Ca+natCa. The observed anisotropy corresponds to a negative elliptic flow signal for Eta mesons, indicating a preferred emission perpendicular to the reaction plane. In contrast, only small azimuthal anisotropies are observed for ăo mesons. This may indicate that Eta mesons freeze out earlier from the central interactiregion than pions.
