abstract = "In this work we investigate the response of the low latitude
ionosphere to Solar Wind High-speed streams (SWHSSs) and
Corotating Interaction Regions (CIRs)-driven recurrent geomagnetic
activity during low and descending phase of solar activity of the
solar cycle 23. Intense magnetic field regions called Corotating
Interaction Regions or CIRs are created by the interaction of fast
streams and slow streams ejected by long duration coronal holes in
Sun. This interaction leads to an increase in the mean
interplanetary magnetic field (IMF) which causes moderate and
recurrent geomagnetic storms when interacts with the Earths
magnetosphere. The ionosphere can be affected by several ways,
such as an increase (or decrease) of the plasma density,
intensification of plasma instabilities during post-sunset or
post-midnight hours and subsequent development of plasma
irregularities/spread-F, as well as occurrence of plasma
scintillation. Auroral heating leads to the development of wave
activity and Traveling Ionospheric Disturbances, or TIDs, which
can affect the middle and the low latitude ionosphere. We analyze
the magnetosphere-thermosphere-ionosphere system variation under
the impact of events of CIRs/HSSs, which occurred during the solar
cycle 23, using multi instrument data and discuss its relevance
for Aeronomic and Space Weather studies.",
