Using measurements of 
629.73 Å from the Coronal Diagnostic Spectrometer (CDS) on board
SOHO we report on blinker activity in off-limb
regions above the Northern pole of the Sun.
The blinkers are found to be occurring above a region showing
strong dynamic activity, with evidence for evacuation of
plasma. The presence of blinkers is discussed in terms of
the heating of spicular material.
Key words: Sun: UV radiation / Sun: transition region / Sun: atmosphere
