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 & 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.
