When I missed the January 2019 “Super Blood Wolf Moon Eclipse” (surely an oversell), I missed the chance to see an actual 400-kg meteor impact on the Moon at about 14-18 km/s leaving a crater about 40 m wide just before totality. The event was imaged by many in binoculars and at least five videos from around the world. Just when you’re sure you have seen it all, you miss another great physics-problem-in-the making. And it turns out this isn’t a first; see the earlier video from 2014.
