CDS observations of the quiet Sun network in the chromospheric He I 584.33 A,and transition region O V 629.73 A emission lines over a time period of 29 min are presented. One eruptive event was detected in this time series of data. The parameters of the network eruptive event are derived and the type of this small-scale activity is identified. The lifetime of the event was ~1 min and it was found only in the transition region emission line. This event had no chromospheric counterpart. All O V spectral profiles of the eruptive event were blueshifted and the maximal Doppler shift was -14.7 km/s. During an initial phase of the eruptive event, the O V intensity enhancement factor was 2.3. These parameters indicate that the observed event could be the transition region explosive event but measured with limited resolution of the CDS instrument.
