This incident is Case 13 in Isaac Koi's "Top 100" article, since it was referred to in 95 of the books covered by that article.
Isaac Koi’s “ICES” Rating for this sighting = 5,880 (out of a potential score of 14*14*14*14 i.e. 38,416)
(1) “Impact” Rating of 14 (out of a potential score of 14), because it is Case 13 in Isaac Koi's "Top 100" article.
(2) “Credibility” Rating of 14 (out of a potential score of 14) because something clearly happened and it has been reported accurately. The debate regarding this incident has centered on whether there is a natural explanation for the event, i.e. a debate regarding its Strangeness Rating (below).
(2) “Expert” Rating of 6 (out of a potential score of 14). It is given this slightly below average rating because (at the time of writing) it has not been included in any of the short lists of the best cases produced by various UFO researchers that have been compiled by Isaac Koi (see the “Best UFO Cases" article at PART 3: Existing lists by various individuals), and is it is occasionally mentioned by some UFO researchers as an example of an event having a mundane explanation..
(4)“Strangeness” Rating of 5 (out of a potential score of 14). The sighting has a relatively low strangeness rating since several researchers have put forward plausible evidence that the event had a mundane explanation (i.e. the explosion of an asteroid or comet) rather than requiring a exotic theory to explain the event.
