Context. Co-spatial and co-temporal spectroscopic, imaging and magnetogram data enable us to better understand various solar tran-
sient phenomena. Here, we study brightening events in the transition region of the quiet Sun, also called `blinkers'.
Aims. We aim to investigate the physical mechanism responsible for blinkers.
Methods. An automated blinker identification procedure (BLIP) is used to identify blinker events in SoHO/CDS data. The 3D mag-
netic topology of the magnetic field in the blinker region is reconstructed based on SoHO/MDI magnetogram data.
