<p class="MsoNormal" style="text-align:justify"><span style="font-size:12.0pt;line-height:115%;font-family:"Times New Roman",serif">In this session we solicit talks on recent advances in studies over different time and special scales in auroral activity, auroral
ionosphere and thermosphere and their impacts on magnetosphere-ionosphere (M-I) coupling. Satellite- and ground- observations continue to reveal many new auroral phenomena. Citizen scientists also recently discovered Steve aurora and are now providing real-time
auroral boundary specification. Waves in the magnetosphere, such as electromagnetic ion cyclotron waves, not only cause ion pitch angle scattering but also lead to radiation belt electron loss. Joule and particle heating in the auroral regions disturbs the
polar ionosphere and thermosphere and affects the M-I coupling efficiency. Modeling and predicting global auroral energy input capturing smaller scale behavior remains a challenge. We welcome all contributions describing auroral related (observations, modeling
or theoretical) studies under different solar and geomagnetic conditions. <o:p>
