NoteThe visible length of the entire event was between around 20 & 40 degrees, it stretched a surprising distance across the sky. I spotted no other objects of any kind, looking around for about 3-5 minutes. I truly wish I had a glasses-mounted camera, it was spectacular and no one near me caught it on film. (I doubt they reported it.) Best of luck tracking it.

NoteThe trail of the object was unusually bright and seemed to hang in the air for just a little longer than I expected. The trail was very prominent but slightly feathered, and had a slight shimmer, like the object was flaking off a large amount if glowing hot dust & flecks. This resulted in a very sharp trail with a slight bloom around it. The bloom expanded and brightened at the point of fragmentation, then narrowed down and reverted to a more defined shape. I suspect the main object likely shed most of the source material for the bloom during the turbulence of fragmentation.

NoteHalfway through it's visible movement across the sky, there was a distinct flash, and a second bright object began trailing behind the first, starting very close but falling behind quickly during the second half of the event, fading from view before the main object did. From my viewing angle, it deviated only a couple degrees at most from the trajectory of the main object while visible. There was a distinct pale orange hue at the point of the flash (color hex #ffba94 is close) and in the trail for a short distance afterwards before shifting to light yellow and pale blue, then back to bright white. The drop-off fragment was almost completely faded out by the time the main object's transition from orange to white was completed.
