Space weather simulation exercice at ESOC

The exercise replicated the effects of a catastrophic solar storm on satellite operations to test the team’s ability to respond without satellite navigation and under severe electronic disruption.

Video of the explosion of the Sun during the 2003 Halloween solar storm, captured by the EIT instrument onboard the ESA/NASA SOHO satellite. Snow-like lines in the images correspond to the saturation of the camera detectors due to the impact of high-energy particles originated in the solar active region.
