Dear Friends,
I have got an information through some intermediaries that your
list dealt a couple of days ago with the 10 May fireball above
southern Moravia (or above eastern Austria, according to other
observers). I would like to inform you that this fireball was
mentioned by many participants of the Hungarian amateur astronomers'
mailing list Csilla.
The fireball itself was observed by one only observer in town Gyor
(in
NW Hungary, on the bank of Danube). It is important, however, that
this
single person observed the birth of a funny, very huge cloud formation
from the track of the fireball. This huge cloud formation, seen on the
page

(photo by Viktor Veres, reporter of the Hungarian newspaper Nepszava)
was
observed from many parts of Hungary, from considerably great
distances:
from Gyor, Budapest, Paks (near to centre of Hungary, on the bank of
Danube), etc. during several hours, beginning with its birth just
after
the fireball event, and ending with comlete darkness.
The two facts,
1) that it was observed from distances 200-300 kilometres or more;
2)
that it was illuminated white above the dark town and above red
or dark normal clouds
means, that it was formed in very great hights, likely above 100 km,
or,
may be, above 150 km in the thermosphere. It means at the same time
that
the sizes of the cloud formation were also very great, perhaps in the
100
km order of magnitudes.
Sincerely yours,
George Valas
