Hi all,
it looks like a large piece of a Jupiter-family comet:
Radiant (apparent ground-fixed, epoch of date):
  R.A.      = 164.25953 deg
  Dec       =  +6.18621 deg
  Azimuth   =  82.37776 deg
  Elevation =  +2.03158 deg
  Vavg      =  34.01099 km/s
  Vinit     =  34.11634 km/s
Radiant (geocentric, J2000):
  R.A.   = 165.92616 deg
  Dec    =  +3.82362 deg
  Vg     =  31.96032 km/s
  Vinf   =  33.83580 km/s
  Zc     =  87.97592 deg
  Zg     =  91.12807 deg
  La Sun = 179.328848 deg
  a      =   2.556608 AU
  e      =   0.884846
  i      =   2.925112 deg
  peri   = 239.667267 deg
  node   = 359.309870 deg
  Pi     = 238.977136 deg
  q      =   0.294404 AU
  f      = 120.353798 deg
  M      =   9.783826 deg
  Q      =   4.818811 AU
  n      =   0.241106 deg/day
  T      =   4.087868 years
  Last perihelion JD = 2459074.084069 (2020-08-12 14:01:03.590173)
  Tj     =   2.687834

The parent body search is inconclusive (minimum D_SH of 0.155), and that part of the parameter space is densely populated so anything like that is just random chance. Note that the map does not contain the complete meteor, last 1/4 is missing becuase there were already more than enough points for a good trajectory solution.
Nothing to write home about really...

If someone really wants to reduce all stations, I can send them the raw files.

Hi all,
thank you all for a quick response, we have it from 8 GMN stations, and it was detected on most. I will make a quick solution just to see if the orbit is interesting, and if it is, we'll make a more detailed reduction. I'm attaching a few images from various stations, most of which were already posted here.

I got it on UFO capture, and can forward files about 24 hours from now when I get home. Regards,  Jim Rowe

this is exciting, looks like we have another one after that one over Germany on Sep. 15th, with path over 500km long.
I can do the same reduction for this one, just send me your .config and platerpar files, along with FF and FR files featuring the event, I will do my best, as time allows.

Hi Kees,

I saw this too on BE0001 in Grapfontaine, which is in the South East of Belgium not far from the Luxembourg-French-Belgian border. It took 3 fits-files for its capture. I first rejected it as false detection as I thought it was something man made passing low over the forests in Grapfontaine. But when I did the CAMS confirmation on DE0001 (owned by Uwe Glässner) I saw it too and only then I realized this had to be very high in the atmosphere somewhere over the north of the Netherlands as seen from the configuration of the camera FoVs. 

BE0002 at my home did not capture it as after 2h UT we got under a thick mist layer (as thick as split pea soup).  From the camera positions I expect NL0004, NL0008, NL000C and perhaps NL000A and DE0004 captured this too.

It reminds me of an Earthgrazer we got over CAMS BeNeLux on 16 February 2018 which moved over 450km but with a velocity that might indicate it was an extraterrestrial meteoroid, it bounced on the atmosphere and sent back to sender ;-).

Hello, Kes!

Save the FR files as well, they should be in same folder as the FF ones,
having same name timestamp as FF ones - from those you may have much
more precise measurements (there are enough stars on images to have a
decent fit, no worries) and nicer video.

All the best,
