An analysis of K+\penalty1000-\hskip0ptd total cross section data is undertaken to explore possible effects of the recently observed resonance in the S=+1 hadronic system with mass around 1.55\phantom\rule0.3em0exGeV. It is found that a structure corresponding to the resonance is visible in the data. The width consistent with the observed deviation from background is found to be 0.9\ifmmode±\else\textpm\fi0.3\phantom\rule0.3em0exMeV and the mass is 1.559\ifmmode±\else\textpm\fi0.003\phantom\rule0.3em0exGeV∕c2 for spin parity (1)/(2)+ and 1.547\ifmmode±\else\textpm\fi0.002\phantom\rule0.3em0exGeV∕c2 for (1)/(2)^\ensuremath-. The errors are one standard deviation and statistical only.
