First off, Mike Hankey deserves special <\/span><span style=\"font-size: 10pt;\">notice since often the first indication we have of a new potential fall is the<\/span><span style=\"font-size: 10pt;\">AMS website that he maintains. Marc Fries was the first to spot the nice <\/span><span style=\"font-size: 10pt;\">Lubbock radar returns for this fall &#8212; less than 18 hours after the event! I <\/span><span style=\"font-size: 10pt;\">compiled those, and additional returns I found in the Amarillo radar, and <\/span><span style=\"font-size: 10pt;\">then went on a search for seismic signatures or videos that could be used <\/span><span style=\"font-size: 10pt;\">to pin down the time of the event. One Youtube video surfaced right away, <\/span><span style=\"font-size: 10pt;\">taken from a dashcam on highway 183 near Euless, Texas:&#8221; (Rob Matson)<\/span><\/p>\n<p><strong>Bolide seen from 183 (westbound) in Euless (near Fort Worth) in Texas<\/strong><\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/qMkeVGSlV7o\" width=\"1280\" height=\"720\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p style=\"text-align: left; padding-left: 30px;\"><span style=\"font-size: 10pt;\">&#8220;Pat Branch did some quick work measuring terminus angles, concluding that <\/span><span style=\"font-size: 10pt;\">the vector lined up perfectly with the radar returns east of Lubbock. I soon <\/span><span style=\"font-size: 10pt;\">located two more videos, one from some still undetermined location near <\/span><span style=\"font-size: 10pt;\">Augusta, Kansas (east of Wichita) and some 580 km (!) from the fall:&#8221; (Rob Matson)<\/span><\/p>\n<p><strong>Recording from Augusta, Kansas<\/strong><\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/YPDoZYfH4ko\" width=\"1280\" height=\"720\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p style=\"padding-left: 60px;\"><span style=\"font-size: 10pt;\">&#8220;and another from a dashcam near Edmond, Oklahoma (north of Oklahoma City)&#8221;<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><strong>Recording from Edmond, Oklahoma (north of Oklahoma City)<\/strong><\/span><\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/qPb7jrtX4p0\" width=\"1280\" height=\"720\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p style=\"padding-left: 30px;\"><span style=\"font-size: 10pt;\">&#8220;Pat Branch was successful in contacting the driver of this car who provided <\/span><span style=\"font-size: 10pt;\">his exact location. There are numerous landmarks in this video that allowed <\/span><span style=\"font-size: 10pt;\">me to determine reasonably accurate starting and ending directions. <\/span><span style=\"font-size: 10pt;\">Triangulating this video with the one from Euless led to a fairly steep fireball entry angle <\/span><span style=\"font-size: 10pt;\">and a nearly due west trajectory.<\/span><\/p>\n<p style=\"padding-left: 30px;\"><span style=\"font-size: 10pt;\">However, upper atmospheric winds were relatively strong (over 100 mph to <\/span><span style=\"font-size: 10pt;\">the southeast,) and not surprisingly this is the trend we see in the radar <\/span><span style=\"font-size: 10pt;\">returns. All that remained was to get an accurate time for the event so that meteorite <\/span><span style=\"font-size: 10pt;\">masses could be estimated (based on the time delay between the fall and <\/span><span style=\"font-size: 10pt;\">when various radar volumes were scanned). Unfortunately, none of the <\/span><span style=\"font-size: 10pt;\">three videos above has a sufficiently accurate timetag.<\/span><\/p>\n<p style=\"padding-left: 30px;\"><span style=\"font-size: 10pt;\">But here again Pat came to the rescue. Rob Ferguson (the provider of the <\/span><span style=\"font-size: 10pt;\">Edmond, OK dashcam) emailed Pat telling him that the fireball was also <\/span><span style=\"font-size: 10pt;\">captured by the Oklahoma Dept. of Emergency Management&#8217;s tower cam, <\/span><span style=\"font-size: 10pt;\">and that a friend of his (Putnam Reiter) works there and pulled the video for <\/span><span style=\"font-size: 10pt;\">him. This has a great, unobstructed view of the event, being up on a tower <\/span><span style=\"font-size: 10pt;\">some 200 feet! Most importantly, it has a very accurate timetag, being <\/span><span style=\"font-size: 10pt;\">regularly synced with a NTP server. So we now knew the beginning of the <\/span><span style=\"font-size: 10pt;\">event was at 3:44:08 UT (21:44:08 CST). I determined that the earliest radar <\/span><span style=\"font-size: 10pt;\">returns of the fall were from Amarillo NEXRAD at 3:45:49.7, just 99 seconds <\/span><span style=\"font-size: 10pt;\">after the beginning of dark flight (~21:44:11 UT). This was how we knew <\/span><span style=\"font-size: 10pt;\">meteorites were on the ground for sure, since dust or even small pebbles <\/span><span style=\"font-size: 10pt;\">can&#8217;t fall that far in less than 2 minutes.&#8221;<\/span><br \/>\n<span style=\"font-size: 10pt;\"> (Rob Matson)<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Last update (Feb. 29) On February 29, 2016 Sonny Clary reported on his website * that Terry Scott and himself had found a 36.1 gram specimen in a cotton field near Crosbyton, Texas (~ 33\u00b039&#8217;34.3&#8243;N&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[96,97,47],"tags":[118,1832],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/7865"}],"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=7865"}],"version-history":[{"count":29,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/7865\/revisions"}],"predecessor-version":[{"id":7887,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/7865\/revisions\/7887"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=7865"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=7865"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=7865"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
