bright baloon like ufo with light circulating under it in brockton Mass. in 1989 .

I was 7 years old at the time. My mom, my step dad, my aunt, my uncle, my two sleeping sisters and I were walking home from my uncle's birthday party. I remember my mom saying "ooh look how big the moon is tonight". My uncle said in responce "If that's the moon, then what is that?" everyone froze and stared at the huge object that seemed to look like a big glowing baloon. It was like a light bulb! and it had colors circling on the bottom. I was so scared that I jumped behind some bushes on the right of the sidewalk. My step dad and my my mom were arguing over what it was. My step dad said it was just a baloon lighted from the inside, while my mom told him it couldn't be because it had no sign or seemed to advertise anything. I am sending you this because around that time there seemed to be other reports. please tell me if there were any. I want to confirm if it was really an unidentified craft or some baloon. At the time of the sighting it was over some houses and disappeared a couple of times behind some trees. please let me know if anything comes up.
Date is approximate.  PD
