It was a short duration event that definitely broke up indicating to me that either a vehicle exploded or a meteor fragmented in several smaller pieces. I did not hear anything though nor did I see a bright flash. There might have been a luminous streak during fragmentation but I'm not sure. I definitely saw multiple glowing objects trailing behind the main object. Everything disappeared with 2 seconds.

Remarks
I first saw a glowing dot in the southwest at a high altitude (60-70 degrees) that quickly broke up into at least 2 or 3 trailing dots. After a second or two they all disappeared
