The 2009 Sulawesi superbolide was an atmospheric fireball blast over Indonesia on October 8, 2009, at approximately 03:00 UTC, near the coastal city of Bone in South Sulawesi, island of Sulawesi. The meteoritic impactor broke up at an estimated height of 15–20 km. The impact energy is estimated in the 10 to 50 kiloton TNT equivalent range with the higher end of this range being more likely. Likely size of impactor was 5–10 m diameter.[1][2][3][4]
