Total Solar Eclipse Festivities Across North America Precede Global Yuri’s Night Celebrations

A week of astronomical and astronautical merriment awaits revelers at a slew of events celebrating the coming total solar eclipse and commemorating humankind’s first foray into space. 5 multi-day viewing parties are planned: Texas Eclipse Festival (April 5-9), KerrClipse Music Festival (April 5-9), Cosmic Eclipse Experience (April 6-9), ROC The Eclipse (April 6-8), and Eclipse-O-Rama (April 7-9). The 4 minute and 28 second totality path of the April 8 eclipse will begin ~370 km north of the Marquesas Islands, make landfall off the Pacific coast of Mexico at 16:38 UTC, crossing population centers in Texas, Arkansas, Missouri, Indiana, Ohio, New York, Ontario, Quebec, and Nova Scotia. The corona visible during this eclipse is expected to be especially prominent given increased magnetic field activity, coinciding with the peak of the 11-year solar cycle. NASA will launch 3 Atmospheric Perturbations around Eclipse Path (APEP) sounding rockets from Wallops Flight Facility for Embry-Riddle Aeronautical University-led study of ionosphere during the eclipse. Studies will also be conducted via high altitude balloon, jet plane, and ham radio. From April 1 – May 11, first human spaceflight by Yuri Gagarin will be celebrated around the world: at 30 events in Europe, North America, Asia, Australia / New Zealand, and South America. Yuri’s Night: LA on April 8 at the California Science Center will feature NASA Astronaut Jessica Watkins, actress Tawny Newsome, DJ Doorly, game designer Gray Bright, aeronautical engineer Chris Boshuizen, and Inspiration4 commercial astronaut Sian Proctor.
