Hot on the heels of last week's flying horse spotted hovering over a Mexican volcano comes news of a two-for-one UFO sighting. A group of UFO fans in Florida have reported – and filmed – a pair of mysterious lights in the sky.

What's more, the Center for the Study of Extraterrestrial Intelligence (CSETI) say they "summoned up" the visitation by "meditating". Claims that the objects bear a strong resemblance to nautical flares are completely unfounded, they say.

Website Inquisitr reports that the group was holding a $2,500 training session to teach members how to communicate with alien craft. As the attendees focussed on summoning spaceships, two bright lights appeared out at sea on the horizon.

The lights were seen on 27 January from Vero Beach and the group insists that the only possible explanation is alien craft. Other UFO enthusiasts are more sceptical, pointing out that the movement of the glowing orbs would be consistent with flares.

CSETI, whose initials might be confused by the unwary with those of SETI, the non-profit group which has worked unsuccessfully with Nasa since 1984 to try to find extra-terrestrial life, is run by a former A&E doctor, Steven Greer.

The group's website does not disclose whether Dr Greer owns a boat, or knows somebody who does.

UFO sightings: 'Flying horse' seen near Mexican volcano

03 February

When is a flying horse not a flying horse? When it's an alien spaceship, a drone - or possibly just a speck of dirt on a camera lens in Mexico.

The Huffington Post reports that a UFO resembling a dark, airborne equine has put in a brief appearance on a webcam which streams images of the Volcano Colima in the west of the country.

To the uninitiated, it's not immediately obvious that the small black speck is anything more than some dirt or a particularly uninteresting fly. But UFO spotters are agog, says the Post.

This isn't the first 'sighting' of aliens around Mexican volcanoes: in 2012, says the Daily Mail, a cigar-shaped object cropped up on film of the crater of Popocatepetl. In November last year a white blur was filmed near the same volcano.

The Mail quotes one Mexican UFO enthusiast, Eufrasio Gonzales Carrasco, 35, who said: "There has been a fair bit of activity around these volcanoes and this latest sighting just adds to the mystery. There must be something about volcanoes that draws extra-terrestrials to them. Perhaps they are collecting samples from our planet to take back home."

The Huffington Post has an alternative explanation, suggesting that amateur drone operators may be attracted to volcanoes to record spectacular footage, which can excite the credulous when the drones crop up on film.

The Mexican authorities accept the drone theory. A spokesman from the country's Civil Protection of the Ministry of Interior said: "It is most likely a drone of some sort. We are looking into it."
