Korlevic ezt irta a jelenségről:

(Mzs)

It was indeed a very special sight to see a fireball at
midday 12:07 +-2 local time, but was _not_ the fireball
shown on the news.

* Till now we have no video of the fireball (searching them).
* No satellite data yet.
* What we have are pictures (need to be calibrated on situ)
* Some fifty eyewitness´s descriptions.
* electrophonic sounds and terminal blast where heard.
* We have the indications that both the Croatian and Slovene seismic
     network was able to register the low frequency vibration/ explosion
    sound 1.5-2 minutes after the terminal flare.

The reconstruction of the photometric curve is not a very
promising for a large meteorite fall (from Cepleha´s fireballs
photometric curves). The first, possible, fragmentation was
followed by a powerful terminal flare and two
micrometeorites/recondensation debris cloud.
The possible strewnfield/larger micrometeorites fall lies
in the fosest regions of the the Croatian-Slovene border.

    More on pictures, calibrations, eyewitnesses interviews, data
reductions, strewnfield dust samples collections is going to bi
done/finished during the "Visnjan school of Astronomy" to be held
from 05-15 of August: http://www.astro.hr/vsa2007/

      So, if the Slovene colleagues are not coming with the
meteorite find from the "Kocevlje forest", we need to wait
the end of August for some reliable data.
