Query: Beyond the known baryon resonances   eta photoproduction data on the proton up to E=2 GeV are interpreted within a
chiral constituent quark formalism, which embodies all known three and four
star resonances. This study confirms the need for a new S11 resonance, with
M=1.780 GeV and Gamma=280 MeV, already introduced in investigating lower energy
data.
