An unknown celestial object fell to the pond in Karki [Karkyu] village on 4th February 2007 at about 10 pm. Despite low temperatures the hole allegedly remained unfrozen for two subsequent days.

The place of the incident was visited by Radiating Control Service and a commission from Latvian Ministry of Environment. Unfortunately members of both commissions weren't able to give a reasonable explanation. Andriejs Salmins - head of the public service of Radiating Control stated that first measurements at the place of incident didn't reveal anything unusual but subsequent procedures conducted at the edge of the aperture revealed strongly raised radioactive background - Latvian sources said.

But it wasn't the end of revelations.

As it turned out, repeated measurements conducted just after the aforementioned ones, didn't found any anomalies.

First information on the event emerged on 13th February in "Degpunkta" broadcast of Latvian National Television where the incident was reported as an event from 12th February. In fact it took place a week before.
