From the document: "The Cybersecurity and Infrastructure Security Agency (CISA) compiled a Communications Planning and Resource Guide to be used in support of the 2023 and 2024 solar eclipse [hyperlink] events. The workgroup that compiled this document consists of subject matter experts (SMEs) in the emergency communications/ planning field. [...] North America will experience solar eclipses on Saturday, Oct 14, 2023, and Monday, April 8, 2024, which will impact states in all ten CISA regions. [...] The last total solar eclipse in the US occurred on August 21, 2017. It passed over the US traversing from Oregon across 14 states in a southeast direction exiting from South Carolina. As captured in After Action Reporting (AAR), local Emergency Managers (EMs) and communications professionals found that SLTTs [state, local, tribal and territorial governments] which engaged in early planning and coordination experienced eclipse events that passed without major incident. Prior to the 2017 eclipse, the US had not experienced an eclipse of this scale, which attracted hundreds of thousands of spectators to view the event. Thousands of visitors are expected to migrate to areas in the main eclipse path this year and next, putting a strain on local resources that are organizing support for the events. Finally, solar eclipse events have not received a Special Event Assessment Rating (SEAR). If designated as such, the highest-level SEAR ratings, level 1 and 2, can provide access to federal resources in support of the SLTTs. SEARs are voluntarily submitted special events, which are sent to the Department of Homeland Security (DHS) Office of Operations Coordination by SLTT officials for a risk assessment. Examples of SEAR events have included the Super Bowl, Indianapolis 500, and the Kentucky Derby. Barring future SEAR designations, this document serves as a resource to help SLTTs plan accordingly."
