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 :-)

Hey Rob,
Nice find. A few more reports have come in, one with a nice video.
https://www.amsmeteors.org/members/imo_view/event/2018/1924
The tractor shed seen in the video, I believe is just 200 meters south
of the witness reported location. Looking at the surrounding buildings
I'm pretty sure this is it. The lat/lon for the building in the video
is: -26.743427° 26.222917°
Thanks,
Mike
