On July 25, 2018, at 21h55 UT, the second most energetic fireball of the past 7 months of 2018 was recorded over North-Western Greenland. With a calculated impact energy of 2.1 kt of TNT, it was slighlty less energetic than the Russian daytime event on June 21st, 01h16 UT, (which calculated energy ranged to 2.8 kt of TNT).

The meteoroid entered the atmosphere at a 24 km/s speed. The altitude of the final explosion was calculated to be around 43 km, at coordinates (lat. ~ 76.9°N ; lon. ~ 69.0° W), which is over the North-Western coast of the country, at a 30 km horizontal distance from the sea.
Explosion occured 40 km North of the American Thule Air Base, and was reported by several inhabitants from the nearby village of Qaanaaq, located 60 km North of the terminal explosion. The close proximity to this AirForce Base leads to very fast checks that it was not a Russian missile, which proves not to be.
We’re still here, so they correctly concluded it was not a Russian first strike. There are nearly 2,000 nukes on alert, ready to launch. pic.twitter.com/q01oJfRUp4
