Lighted Unstructured Cloud
The object seemed to be a lighted amorphous cloud like shape.At the regular evening music, fountain, light, gas jet exhibition a strange lighted shape abruptly appeared and hovered for 20 minutes over the crowd.
Many people saw it and pointed, including me and my family.
It made no noise that could be heard over the music and unexpectedly darted off straight up and disappeared into the star lit cloudless sky.
I still remember it vividly.
