Different directions could mean anything...
They were probably unrelated meteors belong to different showers, but for future reference, in the case of meteors belonging to the same shower, they
will always appear to radiate away from an imaginary point (actually a small area of sky) called the "radiant", which is usually in the
constellation that that meteor shower is named after. A bit like the arrows on this photo...
...keep in mind however, that those arrows only indicate possible directions of meteors belonging to the Perseids meteor shower in this case. In
reality, meteors can appear anywhere in the sky, but they will always travel away from the radiant if they belong to the same shower, and you can
always check if a particular meteor belongs to a particular shower by checking to see if this is the case.
You need to find where the constellations are of course, so download this software
and use it to locate your
Meteors that belong to the same shower also usually exhibit similar characteristics, so they are usually the same color and the same speed compared to
others seen at the same distance away from the radiant. This last part is important in determining meteor shower association since the different parts
of the sky that a meteor is seeing in greatly affect the apparent speed of a meteor due to changing perspective.
So after you have seen a meteor and confirmed that it came from a particular radiant, you can further confirm that it was a shower member by observing
the last two aspects of meteor behavior that I mentioned.
Now you'll be able to tell what is what
You can check a list of meteor showers here
or a calender (which I always use)
Incidentally, some predictions for this years Perseids can be found here
According to these predictions, we should expect a slightly above average peak of about 110-120 ZHR (that means under optimum conditions) early in the
morning (between about 5.30-7.20 UT/GMT) on the 12th Aug. this year. Don't just watch that night/morning though.
The nights before and after can be fun too! This year the moon is starting to become a problem in the nights after the shower though, so I'd advise
watching the nights leading up to the 11th/12th, and don't forget, the best activity is usually right before dawn when the radiant is high in the sky
