Abstract:

The most prominent transient event is presented from an extensive search for the transition region internetwork activity in the quiet Sun atmosphere. The basic physical and geometrical parameters of this event are derived from the O VI 1037.61 A emission spectral line. The spatial extent of 11000 km, duration for 9 minutes, intensity enhancements factor of 7 and large Doppler velocities of both signs were estimated for the event. According to these values this event was identified as a transition region blinker.
