Info received from Dennis Young.
Weather permitting...the Perseids prime time is this Monday night ..tuesday morning ...between 2am and 430am for Southwest USA.. locate time. The shower has already been putting on a nice preshow this past week or so but during the primetime it can produce between 70 and 90 per hour.
Looking northeast just below the constellation of Casseipeia(the Big W) is where all the meteors are coming from in the sky. Of course these are just small particles of dirt and dust shed from the comet known as Swift Tuttle with an orbit of about 132 years. Meteors can be seen (anytime) during the night, so please look even if you can only go out for a short while. You have a very good chance of seeing at least one good one that inspires excitement for young or old.
Good luck and enjoy the free celestial show.. next good one is October 21st called the Orionids shower streaming from the more popular comet known as Halleys.
