Sunday night, around 7:00 PM local time, a bright fireball streaked across the western German sky, exploded, and rained chunks of space rock down on the region around Koblenz. One of the largest known chunks put a soccer-ball-sized hole in someone\u2019s roof<\/a>, landing in their bedroom. Fortunately, nobody was hurt. But given the apparent size of the explosion, there must be many more pieces out there for the finding, and a wave of hopeful meteorite hunters has descended upon the region.<\/p>\n

But if you wanted a piece of the action, where exactly would you start looking? How do scientists find meteorites anyway? And what should you do if you happen to see a similar fireball in the night sky?<\/p>\n

Citizen Science
\n\"\"<\/a>Meteorite video-bombs a boring parking lot in Heerlen, NL.<\/p>\n

In the age of always-on dashboard cameras, ubiquitous smartphones, and other video recording devices, it\u2019s hard for a shy meteorite to find a quiet spot out of the public eye. That makes them a lot easier to find than they were in the past. Indeed, the International Meteor Organization, which aggregates amateur meteor observations, received more than 3,200 reports of this one<\/a>, including several\u00a0with video documentation. Some are stunning,<\/a> and others may not even be of the event at all.<\/p>\n

By collecting reports from many locations, they can hope to piece together the meteorite\u2019s trajectory. However, if you look at the individual reports, it\u2019s clear that this is a difficult task. Nobody is expecting a bright fireball to streak across the night sky, so many of the reports are reasonably vague on the details and heavy on the awe.<\/p>\n

This report from [Sophie Z]<\/a>, for instance, is typical. She records where she was and roughly the location in the night sky where the meteorite passed, along with the comment \u201cI\u2019ve never seen anything so amazing and large before in my life.\u201d Other amateur observers are more precise. [David C] (\u201cI have a Ph.D in physics\u201d) managed to record the start and the end heading of the meteorite to a couple of decimal places. He must have had a camera.<\/p>\n

We\u2019d love to know the exact algorithm used for combining the reports. It\u2019s worth noting that reporters get an experience score, and the system presumably takes this into account when producing the average track. However, the system works, though, with 3,200 reports of a once-in-a-lifetime meteorite, it\u2019s bound to come up with a pretty good estimate. But for smaller meteorites, like this one that flew by on Monday night<\/a>, there are fewer observers, and deducing the actual track is a lot more difficult.<\/p>\n

Everyday meteorites are better tracked by taking a more systematic approach. We\u2019ve covered a few of these networks before, because the equipment needed to contribute meaningfully isn\u2019t all that much more complicated than a single-board computer with a network connection, a camera module, and a weatherproof housing to keep it working all year round. We\u2019ve covered the French meteorite-hunting network, Fripon<\/a>, before, and have featured other amateur sky-camera builds to boot<\/a>. But we\u2019re not amateur astronomers, so we\u2019re not in the loop on what the current state of the art is. If you know about coordinated citizen-science meteorite tracking efforts, let us know in the comments.<\/p>\n

Geologists Get Into The Astronomy Game<\/p>\n

This meteorite was big enough and loud enough when it exploded that participation in tracking wasn\u2019t limited to those who are looking up. Geologists at the Karlsruhe Institute for Technology (KIT) found that the explosion registered on their seismometers<\/a>. (Via Heise Online<\/a>.) These have the advantage that they are in very well-known locations with extremely precise timestamps. After all, that\u2019s what they\u2019re used for every day, although the medium that the pressure waves travel through is usually the earth rather than the air.<\/p>\n

This was also a particularly lucky event for the KIT team because it happened over a particularly dense network of seismological stations in the Eifel mountains, allowing for greater resolution. And as they point out, using the sound of the explosion has the additional advantage of not being hindered by light conditions during the day or clouds at night. This makes us think of how easy it would be to set up a distributed system of microphones to do something similar.<\/p>\n

\"\"<\/a><\/p>\n

The KIT track estimate lines up fairly well with the aggregated estimate from amateur observers, but it\u2019s not exactly the same. Who is right? We\u2019ll see where more of the meteorites are found on the ground, presumably, in the next few weeks.<\/p>\n

Meteorite Hunting<\/p>\n

If the meteorite fell through our roof and chunks were scattered all around our bedroom<\/a>, we\u2019d count ourselves lucky. But would we get to keep it? Of course, it depends on the local laws, and in Germany, you can keep the meteorites in most cases, unless the state decides that it\u2019s of special value for whatever reason, and then they get first dibs.<\/p>\n

Apparently, the going rate for meteorites is between 1\u20ac and 5,000\u20ac per gram<\/a>, so we\u2019re not entirely sure that it will cover the damage. Maybe our homeowners\u2019 insurance would? We\u2019ll have to go dig out our policy to be sure, but however that plays out, we\u2019d just be stoked to have the meteorite chunks and a good story.<\/p>\n

While very big fireballs like this are rare, NASA estimates that around 44,000 kg of meteoritic material falls on the Earth every day. (Whoah!) Most of this burns up in the atmosphere, but some falls to the ground. Most of that fraction is in the form of micrometeorites, which are sand-grain-sized bits that are very likely raining down on us every day. Indeed, if you\u2019re interested, you can try to collect them, and all you need is a tarp on the roof or a magnet in your downspout, a good microscope, and a bit of knowledge<\/a>. So if all you want is some extraterrestrial rock, and you\u2019re not worried so much about the size, maybe micrometeorite hunting is the path to success.<\/p>\n
