Witnessed ufo changing colours on June 12th, 2000 - 6 witnessesI am a X standard student from India. Six of our friends were sitting on our school terrace on 12th July 2001 when suddenly the clouds started to move very fast. Then one of us noticed a spherical object changing colour from a metallic silver to a luminous green. It hovered about for about 2 minutes & then it just vanished into thin air! It started raining just after the incident.
