The stones that fell on Kaanda farm

On 11 May 1855 stones rained from the sky over north-western Saaremaa. After the meteorite shower, fragments were picked up on the land of Kaanda farm in Merise village. Scientists named the find Oesel, the island's old name. It is a common stony meteorite, an L chondrite, and its mass was about 6 kg. It holds small olivine and hypersthene grains up to a quarter of a millimetre across. By the old calendar the date was 29 April. It is the first meteorite in Estonia for which eyewitness accounts have survived. The puzzle did not end there. In 2018 the island paper Saarte Hääl asked whether nearby Kaanda lake might itself hide a meteorite crater.

Eesti keeles

11. mail 1855 sadas Loode-Saaremaal taevast kive. Pärast meteoriidisadu korjati kilde üles Merise külas Kaanda talu maadelt. Teadlased nimetasid leiu Oeseliks, saare vana nime järgi. See on tavaline kivimeteoriit, L-kondriit, ja selle mass oli umbes 6 kg. Selles on kuni veerand millimeetri suuruseid oliviini- ja hüperseeniterakesi. Vana kalendri järgi oli kuupäev 29. aprill. See on esimene meteoriit Eestis, mille kohta on säilinud pealtnägijate kirjeldused. Mõistatus ei lõppenud sellega. 2018. aastal küsis saareleht Saarte Hääl, kas lähedal asuv Kaanda järv võib ise peita meteoriidikraatrit.
