There were actually two separate fireballs, they were parallel to each other but one was slightly behind the other. For the naked eye there was a gap between them of a couple of centimetres. The balls were a mixture of yellow and orange with bits breaking off of both fireballs. If a normal shooting star is a width of a finger both of these were the size of a fist. The trails were yellow in colour.
As above items were breaking off the fireballs and burning up.
