the orange orbs

The orange orbs as me and my friend have come to know them were seen in the sky near hull they resembled the hot air candle things that people do on new years eve. These were spoted moveing very rapidly against the wind which was fairly strong this was one night in febuary round about 10 o'clock there were two orange orbs moveing in unison at first glance but when watched for a while they were weaving in and out of each others paths and each kept changeing speeds. Can anyone tell me what they were or if you have seen then. If so where and when
