Witnessed a couple of things tonight and I have to admit I'm a bit freaked now.
I'll start with the details: 
Date: Dec 1st
Location: county Meath, East coast of Ireland
Time: from 7pm
Location spotted: to the north east
Lasted approx 1.15 hrs

I got a phone call from my brother in law to say he saw the lights to the south east. I went outside with my tripod with the hopes of recording them. While I was scanning the sky a huge green (I'm almost sure it was so quick and I was shocked, could have had some blue) ball of light like a meteor, with a large tail. I freaked a bit first but got my phone setup and started recording. Within a few minutes of seeing the other thing the two lights in the video appeared. Please note it's been cloudy for the last few days and this was recording during a break in the clouds. Some of the disappearing could well be from clouds. Also please note this is the unedited video. I took a copy and brightened it but there's nothing else to see really so I'll post this one. To me this looks like conversation, and lots of it. A plane can be seen crossing in the video too and it's funny to watch the "reaction". Almost like the one on top was saying to hide. It got really cloudy at approx 815pm and is starting to rain so I'll take this opportunity to upload this video. I have a good few more but I'll stick them on Imgur tomorrow and update in the comments.
