jupiter

Anyone remember when Jupiter was supposedly getting pelted with asteroids? 
I was a young lad sitting on the lawn with friends looking up in the NW night sky one night. 
We saw a bunch of interesting things those couple days, or weeks, I don't remember. 
The thing that stood out to us the most though was on that night. 
It wasn't much, probably seeing things from being so high on life, not sure... 
but what we saw was an odd, relatively large, at least from our perspective, 
red dot come directly out of the southern pole and enter back on the east. 
I'll never forget it, whatever it was.
