Researcher says a UFO wave swept through Hidalgo between 1991 and 1993
According to CEFP, a Mexican UFO research group, a genuine UFO wave took place in the state of Hidalgo in the early 1990s, and the group dates the start of the phenomenon to April 1991. However, the account was written decades after the alleged events and so far contains few verifiable details.
The earliest date the account names is April 22, 1991. This is when the intensifying wave of UFO sightings would have begun, as written about by Rafael Lara Palmeros, a member of the Mexican UFO research group CEFP. According to Lara Palmeros, between 1991 and 1993 the organization received an extraordinary number of reports of intense UFO activity from the state of Hidalgo, and when the researchers visited the site, they were able to confirm that the phenomenon did indeed go back to 1991. The researcher clearly describes this as a genuine UFO wave.
What do we know, and what don't we?
The available text mentions a single specific date and an unnamed woman as the person who made a report on April 22, 1991, but further details are not known. There is no information on how many people came forward during the three years in question, what exactly the witnesses saw, or whether any photographs or recordings were made of the events. It is also unclear how CEFP's on-site investigation was carried out and by what method the researchers satisfied themselves that the phenomenon was real.
The account comes from a single source, a blog post published in September 2026, which itself refers to an earlier, undated research document. No independent confirmation, official investigation or other contemporary press source is connected to the case so far, so the claim currently rests on the credibility of a single researcher and his organization.
CEFP's work nevertheless highlights a broader pattern: in Mexican UFO literature of the 1980s and 1990s, so-called wave-like periods regularly appear, when many reports accumulate in a given area within a short time. Whether the Hidalgo case is exceptional among these cannot be determined from the current data.
The sober take
The source does not specify exactly what the witnesses saw, so no specific everyday explanation can be established. In similar accounts compiled decades later, it is common for identifiable light phenomena or aircraft to be among them, but no data on this is available in this case.
