Residents in west Wales report seeing 'mysterious blue light' in the sky
Residents have reported seeing a mysterious blue light in the sky between Swansea and Carmarthenshire .
The strange "blob" was spotted from around 6pm onwards on Tuesday 21 January.
One resident from Llanelli , saw the "blue or purple light" at Llangennech and said "it looked like it was coming from the M4, it moved to the right then went off".
Andrea Harries said she saw the strange light at around 6.05pm from her garden in Penllergaer.
She said: "I came out into the garden with the dog and saw a blue, purplish light.
"It was bright but dimming every now and then. It moved over to Pontlliw and then towards Llanelli and then it just went."
She described it as being a "fair size", adding: "There was no noise and at the time there were no planes or anything - I don't know what it was."
Another resident Pixie Fear, 22, saw the light out her window while doing university work at her Pontarddulais home.
She said: "Me and my brother came outside and this blob lit up the sky and flashed on and off. It was just floating through the sky going west. It was huge.
"We did a plane tracker but there were no planes about - it was going between Llanelli and Carmarthen and was so bright.
"It seemed to go pretty far, at least a few miles and quite quickly - bearing in mind it was far away so probably looked slower than it was."
In August 2019, a mysterious blue light was also seen floating over Bristol.
Instead of a UFO, the strange light in fact turned out to be a high-tech train which checks for wear and tear on the overhead electrified wires.
In August 2018, Manchester Evening News also reported a similar sight, which residents described as a "pulsating purple glare".
At the time, a spokesperson for Network Rail said: “We can confirm this was not an unidentified flying object (UFO). It was rather an identified non-flying object (INFO) - namely a railway ballast tamping machine, which uses lasers.”
However, this hasn't yet been confirmed in Wales.
