Equipped with a preliminary strewn field map provided by Pavel Spurn\u00fd on July 14, 2018 and coordinated by Dieter Heinlein the meteorite hunters Ralph Sporn and Martin Neuhofer were sent to the calculated strewn field on 15 July and stayed there until 18 July, mainly to explore the area. Sporn and Neuhofer returned to the strewn field on 22 July and on 24 July around noon Ralph Sporn found Renchen-1 (11.9 g), an almost complete specimen, in a cherry orchard at location 48\u00b034’26.4” N, 8\u00b001’8.8 E<\/a>, about 1.48 km southeast of Renchen.<\/p>\n

On 30 July around noon Pavel Spurn\u00fd transferred another map of the part of the strewn field where larger masses were expected to have fallen to Sporn and Neuhofer who had returned to the strewn field for their third search campaign on 29 July. On 31 July Ralph Sporn and Martin Neuhofer found a large mass of 955 grams (281.420 cm\u00b3) with broken faces next to a small shallow impact pit on the eastern edge of a meadow near the Heuweg<\/em>, east of Holchenbach<\/em> in the south of the communal district Rheinau between the forests Korker Wald<\/em> and H\u00fcrbewald<\/em> about 5.4 km north-west of Renchen (48.610222, 7.948167)<\/a>. The unbroken chipped side (View A in photo below) of the meteorite was up when it was found a few centimeters north of the impact pit in the dry grass. The locations of Renchen-1 and Renchen-2 were used by Dr Spurn\u00fd to refine his strewn field calculation by 8 August 2018. Radio nuclides of the specimen have been measured at Max-Planck-Institut f\u00fcr Kernphysik (MPIK) in Heidelberg. The soil around and including the impact hole has been cut out and saved by the finders, similar to what has recently been done with the impact pits of the Stubenberg and Mangui falls. A chunk of 81.6 grams which includes the type specimen of 20.9 grams was cut off the main mass on 15 November 2018 which left the remaining main mass with a weight of 868 grams.<\/p>\n\n
