A meteor explosion over the New Hampshire-Massachusetts border on May 31, 2026, created a loud sonic boom heard across six states and as far as Montreal. The event, occurring around 2 PM local time, caused widespread reports of ground shaking, fireball sightings, and a double boom that startled residents and pets. Authorities confirmed no public safety threat, with NASA estimating the 1-meter-wide meteor disintegrated at 40 miles altitude, releasing energy equivalent to 300 tons of TNT. The American Meteor Society received hundreds of reports spanning from Delaware to Montreal, making it one of the most widely observed meteor events in recent history. Der Spiegel+2
The meteor was approximately 0.9 to 1 meter (3 feet) in diameter and weighed as much as an elephant. Traveling at 120,000 km/h (75,000 mph), it entered the atmosphere near the New Hampshire-Massachusetts border north of Boston before breaking apart. Satellite data captured a distinct flash correlating with eyewitness accounts of the fireball and sonic boom. The event occurred on May 30-31, with some reports extending into June 2. CBC News+2
NASA and meteorologists analyzed satellite imagery showing the meteor's atmospheric entry as lightning-like patterns. The explosion's energy release was equivalent to 300 tons of TNT, with no ground impact or debris found. The American Meteor Society confirmed the meteor's complete atmospheric burn-up. This marked a significant event following another East Coast meteor occurrence earlier in the week. Der Spiegel+2
Police departments across Massachusetts and neighboring states fielded hundreds of calls about the loud explosion and ground shaking. Social media was flooded with questions and reports from Delaware to Montreal. Authorities confirmed no damage or injuries, though the event caused widespread alarm and speculation among residents. The American Meteor Society's report volume highlighted the event's exceptional visibility. China.org+2
