I witnessed an incrediable event in January. Riding back from the shops early evening and there were 3 guys staring into the sky. Had been continual local newspaper stories all through December of sightings. Anyway what i saw was a large ball of light the keep scanning the sky back and forth quite low. It kept getting larger and smaller which i think was because it was rapidly moving back and forth over two areas of woodland. Then it rose in the sky and started moving erratically jiggling around. It then just cruized off low in the sky and was gone. There's been loads of similar sightings since, many of which are on you tube.
I should add that I thought I had saw another one a few weeks ago. It was a bright slowly moving light the moved constantly and slowly with then just dropped. This i am certain was a chinese latern that are set of from a point near me.
