Another 'Tabletop Exercise' at Johns Hopkins becomes Worldwide Event
The Johns Hopkins Applied Physics Laboratory released the results of the nation’s first end-to-end Space Weather Tabletop Exercise (TTX). The Space Weather Prediction Center was a key participant in this TTX, which was held May 8-9, 2024. Read the brief synopsis about the full report to get a general understanding of the exercise’s intent and key findings. The full After Action Report(link is external) is now available to the public. Ironically, this TTX took place just as the largest geomagnetic storm in over 20 years was about to unfold - The G5 (Extreme) storm of May 10-11, 2024, so both the simulated actions of the TTX and the real-world needs of the country were managed together.
