Time is unfortunately very approximate it could have been between 3:20 and 4:20 am so I have my best guess. Seen while driving. Meteor was headed almost exactly south. Very bright, outshone the light of the street lamps.

Terminal flash
Observation
Yes
Remarks
The original look was bright green solid light like staring at a starboard signal. It abruptly stopped for less than a quarter second then flashed twice in a small and brief orange burst the color and brightness of a high altitude rocket engine (think nearly second stage) with visible shattering as the color disappeared. The bursts were one after the other with darkness in between lasted about a quarter second combined from pop to loss of visibility and was the same approximate size of the green dot of the fireball though much diminished in brightness. Close the the brightness and size of Jupiter
Fragmentation
Observation
Yes
Remarks
Reference previous entry, fragmentation was visible only due to the pieces glowing during detonation. It was an obvious break up but did not stay glowing long enough to be seen much past it’s initial diameter of around 1-2 mm from my perspective.
