This happened in Oct-Nov 2007 don't remember exact date.I am from India (Chennai).I happen to notice 3 stars in an inverted triangle position on the west side everyday.As i am in the 1st floor and have a balcony i put on some music in my room and stand in the balcony every evening and noticed this stars formation to be peculiar.One day as i was looking at these 3 stars,the 1st star was not that bright,2nd was brighter than the 1st and the 3rd one the brightest of all. As i was watching i suddenly noticed another star coming from the 1st star moving slowly to the 3rd star and when it came very closely to the 3rd star it became more brighter than the 3rd star and disappeared in about 5 seconds.I was shocked to see this and after about 2-3 minutes again one more star came from near the 1st star and to the 3rd star and disappeared in the same manner.Time was from 6:30pm-7pm.After this i haven't seen this inverted triangle stars formation,but have noticed strange objects flying in the sky,and i believe in UFO's as i had seen one when i was about 15 years old.
