These include coronal mass ejections, interplanetary shocks, and solar energetic particles. Predicting and mitigating extreme space weather is vital to protect sensitive systems such as communication, navigation, power grids, and aviation. Post-event analyses enhance predictive models, helping safeguard critical infrastructure.</span></p><p style="color: rgb(14, 16, 26); background: none; margin-top: 0pt; margin-bottom: 0pt;"><span data-preserver-spaces="true" style="background: none; margin-top: 0pt; margin-bottom: 0pt;"> </span></p><p style="color: rgb(14, 16, 26); background: none; margin-top: 0pt; margin-bottom: 0pt;"></p><p style="color: rgb(14, 16, 26); background: none; margin-top: 0pt; margin-bottom: 0pt;"><span data-preserver-spaces="true" style="background: none; margin-top: 0pt; margin-bottom: 0pt;">This session highlights the state of space weather products and explores innovations to understand their impacts on infrastructure better. Topics include forecasting, satellite observations, model development, data assimilation, machine learning, and solar, geomagnetic, and ionospheric activity indices. Cross-disciplinary approaches and studies on applications such as aviation, pipelines, power grids, space flights, and auroral tourism are encouraged.</span></p><p style="color: rgb(14, 16, 26); background: none;
