Apparent meteorite fall at ~16.56 UTC (?) on 10 July 2021 (OC, 2.76 kg) near El Ramón de las Yaguas, Santiago de Cuba province, Cuba

Last update: 5 September 2021

On 16 July the Ciencia Tecnología y Medio Ambiente (CITMA) of Cuba reported that on 10 July a 2.76-kilogram meteorite (13.7 cm x 12.9 cm x 9.8 cm) was found in a clearing, about 12 metres from a small house, at location ~ 20°02’51.4″N, 75°31’44.1″W , about one kilometre northwest of the village El Ramón de las Yaguas in Santiago de Cuba. The Delegación de Santiago was informed about the incident on 10 July by Co. Máximo de la Cruz Torres, president of the Popular Council of El Ramón de Las Yaguas, Santiago de Cuba municipality, Santiago de Cuba province. Some residents of Ramón de las Yaguas claim they saw a bolide and its dust trail. Then they heard some thundering noise shortly before 16.56 UTC. On 15 July members of CITMA went to the area to investigate the matter. They took the meteorite and sent it to Havana for analysis by experts from the Institute of Geophysics and Astronomy (IGA) of the Environment Agency (AMA). On 2 September the Institute of Geophysics and Astronomy (IGA) reported that it has “graphic records of the seismic noise, caused by the explosion of the meteorite when entering the Earth’s atmosphere, over the territory of Santiago de Cuba” shortly before 16.56 UTC in the afternoon of 10 July.

We believe that during the classification process of this meteorite a thorough analysis of short-lived cosmogenic radionuclides with very short half-lives must be performed very quickly. It must be confirmed with certainty that this meteorite actually fell on 10 July and not earlier.

Details of graphic records of the explosion, upon entry into the atmosphere of the cosmic object, captured in three seismological stations in the Cuban East, sent to the IGA by the Central Station of CENAIS, Santiago de Cuba. The coincidence in UTC time of the record of the Río Carpintero Seismological Station is circulated in red, and a small offset in real time, in the two remaining Stations, due to the greater distance of the latter in relation to the place of the explosion and meteorite fall.
