Re: [meteorite-list] Minor planet impactor witnessed over Botswana
Hi Mike, hi Rob, thank you for this outstanding news. Video seems very promising for a meteorite fall. This is the 3rd meteoroid detected prior of the fall. (See Wikipedia) 1. 20081007 Sudan_TC3_Almahatta Sita 2. 20140102 Atlantic Ocean NE to Brasil 2014 AA (3. 20151113 Sri Lanka WT1190F --> 11,3 km/s reentry of translunar injection module from Lunar Prospector, 1998) 3. 20180602 Botswana ZLAF9B2 Looking forward to the next one :-) --Thomas Gesendet: Sonntag, 03.

[meteorite-list] Minor planet impactor witnessed over Botswana
Hi All, Catalina Sky Survey has done it again -- discovery of an impacting NEO, this time just 8 1/2 hours prior to impact. CSS discovered the NEO at 8:14 UT today (1:14 am MST), and a bright vapor trail was seen to the north of observer Dhiraj S in Botswana (24° 37' 21'' S, 25° 54' 57'' E) at 16:44 UT, consistent with both the time and location of the asteroid's predicted trajectory: http://www.amsmeteors.org/members/imo_view/report/142364 Bill Gray's time/location plot for predicted impact: https://projectpluto.com/temp/z.png Yellow cross-hairs are the observer's location. Asteroid size pretty similar to that of impactor 2008 TC3 that ultimately resulted in meteorites recovered from Almahata Sitta in northern Sudan. Unfortunately, due to the short time between discovery and impact, very few observations (12?) made of the impacting body (temporary designation ZLAF9B2) on this occasion. Compare that with almost 800 observations of 2008 TC3. --Rob __ Visit our Facebook page https://www.facebook.com/meteoritecentral and the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list
