There are numerous stories in the press about sightings in this area.
Here is a link to a blog that I feel is quite similar to yours -

Here is also a story from the local news paper. So at least you know the british government is aware of UFO activity in the area.
UFO sightings sparked MoD probe May 28 2005 Sam Burson, Western Mail
A SPATE of UFO sightings in Wales prompted a secret Ministry of Defence investigation, newly-released information has revealed.
The clamour around the possibility of "little green men" visiting Pembrokeshire forced Government officials to look into the situation in the late
1970s.
There were numerous tabloid reports, including one of an entire class of schoolchildren claiming to have seen a UFO landing.
Many others reported being petrified by a strange silver alien.
It all happened in what became known as the Broad Haven Triangle.
Canny tourist operators even started running UFO sighting weekends.
But new documents show despite publicly dismissing the reports as hoaxes, defence experts were racing to get answers.
In a letter from May 1977, MoD minister Dr John Gilbert MP tells officials in the department, "I am being inundated at the present time with
representations about UFOs said to have been seen in Pembrokeshire."
He asks whether any investigations are being carried out.
A reply tells the minister, "We look into detailed reports of unexplained phenomena to see if they have a bearing on the national defences."
But they reassured we were not in danger of alien takeover, saying, "My department has carried out that type of investigation on the reports received
from Wales, but these have been few in recent months.
"No evidence has been revealed to suggest that the alleged sightings in Wales, or indeed those reported from other parts of Great Britain in the
past, contained anything of significance from a defence point of view.
"All I can tell you on the basis of the department's past experience, is that most reports of this nature can usually be referred to a commonplace
object, which may have been observed perhaps from an unusual angle or in somewhat unusual weather or lighting conditions."
However, unbeknown to the minister, the RAF in West Wales was asked to carry out a "discreet" investigation.
An extract of a private memorandum to the Provost and Security Service of the RAF, (effectively the military police), reads, "I should be grateful if
you would have a look at these papers and let me know whether you think some sort of discreet inquiry would be worthwhile.
"What I would really like to know is the volume of local interest and/or alarm, and whether there is a readily discernible rational explanation for
it (perhaps a practical joker), or even whether there is prima facie evidence for a more serious specialist enquiry.
"But I have not committed you in any way, and I have not even told the minister I am consulting you."
The report called for has yet to be released.
Sheffield University's folklore lecturer Dr David Clarke, who uncovered the other documents under the Freedom of Information Act, is now trying to
track it down.
Dr Clarke, who is researching a book called Saucer Full of Secrets about the folklore of UFO sightings, said, "I was really surprised to find
this.
"Generally the MoD dismisses these things and doesn't take them too seriously.
"But to find they ordered an investigation behind the Minster's back is pretty interesting.
