This document is a letter dated June 7, 2001, from Márcio Dillmann de Carvalho of the Grupo de Pesquisas Científico-Ufológicas (GPCU) to the Comando de Defesa Aeroespacial Brasileiro (CONDABRA). The author, writing to Colonel Cavalcante, provides a collection of research materials regarding Unidentified Aerial Phenomena (UAP) sightings in the state of Rio Grande do Sul, Brazil. The correspondence serves as an introduction to several enclosed reports, including a sighting by State Deputy Paulo Azeredo on December 28, 2000, while traveling on the BR 293 highway. Azeredo reported observing three yellowish lights, followed by a bright bluish-white object that appeared to hover near trees and later followed his vehicle. The document also details a wave of sightings in November 2000 across municipalities such as Pelotas, Rio Grande, Pedro Osório, Piratini, and Canguçu. These reports describe various phenomena, including objects in formation, circular and diamond-shaped craft, and instances of physical interference in residences. The author emphasizes the scientific approach of the GPCU and expresses a desire for mutual collaboration with the military command. Additionally, the document includes a copy of a photograph taken by Leomar Prado on April 29, 2001, and partial documentation regarding the U.S. 'Project Silver Bug-1955', which had recently been released under the Freedom of Information Act (FOIA). The author concludes by reiterating the availability of the GPCU's archives for further study.
