Ja. Docobo et al., INVESTIGATION OF A BRIGHT FLYING OBJECT OVER NORTHWEST SPAIN, 1994 JANUARY 18, Meteoritics & planetary science, 33(1), 1998, pp. 57-64
On the early morning of 1994 January 18, a very bright luminous object
crossed the sky of Santiago de Compostela, Spain. From visual sightin
gs, it is concluded that the object wasn't a meteoric fireball (bolide
). A surface ''crater'' in Cando (close to Santiago) with dimensions 2
9 x 13 m and 1.5 m deep was later discovered within 1 km of the projec
ted ''impact'' point of the luminous object. At this site, in addition
to the topsoil, full-grown pine trees >20 m high were thrown downhill
over a nearby road, leaving the downslope edge of the ''crater'' unto
uched and with a steep interior wall (this would not be the case if a
regular landslide were responsible for the transport). Standing trees
below the ''crater'' showed embedded soil and plant residues up to hei
ghts >3 m. No strange materials (meteorites or artifacts) were recover
ed in or close to the ''crater''; all materials belonged to the site a
nd were not shocked; thus, an impact is very improbable. A possible ex
planation capable of reconciling all of the observations is presented.
It hypothesizes an eruption of earth gases to create the crater, with
the rising gas plume then interacting with atmospheric electricity to
produce the propagating fireball that was observed.
