<p class="MsoNormal" style="background-image:initial;background-repeat:initial"><span style="font-size:10.5pt;font-family:'Times New Roman',serif;color:rgb(51,51,51)">Nighttime MSTIDs have long been considered to
be conjugate, exhibiting very similar density patterns at both northern and
southern magnetic hemispheres. However, continuous observations of
mid-latitude plasma structures in the American sector have shown that they do
not always fully map to the opposite hemisphere. Low latitude plasma
bubbles can reach mid latitudes, not only during magnetically disturbed
conditions, but also during quiet epochs. An observer placed at the
boundary between low and mid latitudes could conclude that all plasma
structures at mid latitudes are conjugate. The availability of
distributed observatories and the advent of new satellite constellations make
it possible to conduct continuous and conjugate observations of these processes.
We look for presentations aiming to provide answers to the questions on the
initiation and conjugacy of plasma structures and MSTIDs at low and mid
latitudes and discuss results of recent observations and modeling when views
from both hemispheres are available.</span></p>
