Solar flares can produce x-rays that affect satellite communication in the near-Earth environment, it can degrade or block communication signals. Solar energetic particles can penetrate satellite electronics and cause electrical failure. Coronal Mass Ejections (CME’s) can cause Geomagnetic Storms at Earth and induce extra currents at the ground that can degrade power grids and other infrastructure. All these events are termed space weather and need to be studied, forecasted, and notified in advance to mitigate its effects. In this seminar, we will talk about space weather, its effect, and forecasting capabilities to mitigate its effects.
