There are no reports of flaring, but the object fell to pieces towards the end. Other witnesses from close to the calculated end point have still to be interviewed in situ, but no reports of sounds were made by them. It would appear that the end point height is above 30km. More on Saturday's fireball. Initially, no eye-witnesses reported hearing any sounds after the passage of the fireball, but two people reported hearing loud sounds but had not seen the fireball.
Natural objects are much more common than re-entries and much bigger.
Of course both of us think that the NEO hazard shouldnt be ignored. Why it is unlikely to be a satellite re-entry. The shallow angle of entry of satellites usually gives durations of many tens of seconds. This object was less than 10 and most reports give about 5. The object was very bright.
