Using both charged and neutral components, 2600 multihadronic e+e− annihilation events, recorded at 34 GeV by the CELLO detector at PETRA, have been analysed in a calometric approach. The fraction of energy carried by gamma rays is measured to be fγ = (26.0 ± 0.4 (stat) ± 4.0 (syst)%. The neutral energy flow is seen to follow closely the overall energy flow. From the corrected oblateness distribution, a first order determination of αs is performed. The result is αs = 0.16 ± 0.01 (stat) ± 0.03 (syst).
