We determined the atmospheric trajectory, velocity, and heliocentric orbit using one dedicated AllSky6 meteor camera and three casual video records of the bolide. It was found that the meteorite originated in the vicinity of the 5:2 resonance with Jupiter at heliocentric distance of 2.82 AU. When combined with the bolide energy reported by the U.S. Government sensors (USGS), the pre-atmospheric diameter of the meteoroid was estimated to 2 &#8211; 3 meters and the mass to 10,000 &#8211; 20,000 kg. The meteoroid fragmented heavily in the atmosphere at heights of 46 &#8211; 37 km, under dynamic pressures of 0.7 &#8211; 2 MPa. The recovery of just one meteorite suggests that only a very small part of the original mass reached the ground. The bolide velocity vector was compared with that reported by the USGS. There is good agreement in the radiant but the velocity value has been underestimated by the USGS by almost 1 km\/s. &#8220;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ji\u0159\u00ed Borovi\u010dka, Felix Bettonvil, Gerd Baumgarten, J\u00f6rg Strunk, Mike Hankey, Pavel Spurn\u00fd, Dieter Heinlein Manuscript submitted to Meteoritics &amp; Planetary Science PDF (OPEN ACCESS) Update (9 February 2021): LINK &#8220;The C1-ungrouped carbonaceous chondrite Flensburg fell&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9,5436,96,335,47],"tags":[880,3273,5437,2212,3662,382,1832],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/25591"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=25591"}],"version-history":[{"count":2,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/25591\/revisions"}],"predecessor-version":[{"id":26114,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/25591\/revisions\/26114"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=25591"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=25591"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=25591"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
