Fireballs lighting up the southern Spanish sky on the night of 15th of April - 16th of April.I was in the harbour of Puerto Banus, southern Spain, when I spotted strange light reflections above the harbour. At first I thought it was a plastic banner that had come loose off one of the boats and reflecting the lights of the harbour. I alarmed my friends who thought the same. Next we thought it was fireworks from one of the many nearby beach bars when my friend pointed out that the lights were moving far too quick to be fireworks. As time went on the lights changed into fireballs with the one at the front flashing/burning brightly which made me think that maybe it's an aeroplane on fire and about to crash, leaving trail of burning fireballs behind it, some smaller, some bigger, in different colours. By this time the entire port was looking at the sky (1000's of people). There was no sound coming off these objects. The phenomenon carried on going right across the nightsky and the fireballs only started fading and disappearing when they were almost out of sight to the far East (they had appeard in the west). I have seen meteor showers before but never have they been anything like this in terms of quantity, intensity and how close they seemed above the Earth's surface. Very strange indeed. I don't think they could have been more than 15-20kms above us, however they must have travelled 100's of kms in the space of 60-90 seconds. Has anyone got any explanation for this phenomenon?
