ARE UFOS WATCHING THE U.S. RADIO-ASTRONOMICAL OBSERVATORY AT ARECIBO? MAYBE CONTACT HAS ALREADY OCCURRED?

This document, authored by Jorge Martín and published in 1998, presents a series of reports concerning Unidentified Aerial Phenomena (UAP) sightings in the vicinity of the Arecibo Radio-Astronomical Observatory in Puerto Rico. The text argues that the observatory is a frequent target of UFO activity and suggests that official government sources are deliberately withholding information from the public. The author details several specific accounts, beginning with a 1981 incident involving Señora Gertrudis Mendoza, who reported seeing a bright object and three beings in the Barrio Dominguito area. Subsequent accounts include a 1991-1992 sighting by Felipe Jiménez, who observed a large, disc-shaped object with a cupola, and a 1994 report by José Angel Rodríguez, who claimed to have been followed by a large, silent, glowing object while driving near the observatory. The document also highlights a 1996 incident involving the family of Señora Marina Rivera, where chickens were found dead with mysterious incisions and crushed organs, an event the author links to the 'chupacabras' phenomenon. Throughout the text, the author criticizes the Arecibo Observatory's official explanation that these sightings are merely 'meteorites,' asserting that the observatory staff and government agencies are aware of the true nature of these phenomena but are under instructions to maintain secrecy. The document concludes by emphasizing the need for further investigation and promising future reports on the matter in the publication EVIDENCIA OVNI.
