ABSTRACT
Although there has been advancements in under­
standing the small­scale transient events seen on the
Sun at transition region temperatures, it is still not
clear what is the connection between the events seen
on the disk and those on the limb. In this contri­
bution we investigate di#erent types of short­lived
events, such as spicule­like structures, bi­directional
jets and blinkers. The data selected for this study
were obtained as time series in polar coronal holes
by SUMER and EIT (SoHO). The short exposure
time, a reduced e#ect of the solar rotation at the
poles and the coverage of both on­disk and o#­limb
regions, give us an excellent opportunity to analyse
