Key topics included solar activity, such as solar flares and coronal mass ejections, and their interactions with Earth's magnetosphere, ionosphere, and thermosphere. Discussions also highlighted the impacts of these processes on satellite operations, communication systems, power grids, and Earth's climate, emphasising both immediate space weather effects and longer-term space climate influences on technological and natural systems.</div><div style="margin-top: 0.5em; margin-bottom: 0.5em;"><span style="font-weight: bold;">Confirmed invited speaker:</span><br><ul class="MailOutline"><li><span style="font-weight: bold;">Erika Palmerio</span> (Predictive Science Inc.) will present an overview of "forecasting CME arrival and impact: what should we improve?"</li></ul></div><div style="margin-top: 0.5em; margin-bottom: 0.5em;">We look forward to your valuable contributions and appreciate your attention and interest.</div><div style="margin-top: 0.5em; margin-bottom: 0.5em;">Sincerely yours, session conveners,<br>Guram Kervalishvili,<br>Emilia Kilpua, <br>Olga Malandraki</div><div>
