It looked a bit like a firework or flare exploding! It spread in a triangular shape with about 4 or 5 bits spreading about 30 degrees from the central point then it disappeared!
Fragmentation
Observation
Yes
Remarks
It went from one bright light to about 5 separate smaller lights/lines that spread out in a triangular shape in straight lines! These lights then seemed to spin off in different directions for a split second before quickly disappearing again!
