  The 2009 Perseid Meteor Shower
  Earth is entering a stream of debris from Comet Swift-Tuttle, setting the stage for the 2009 Perseid meteor shower.

  Usually there are some radio propagation effects.

  PERSEID METEOR SHOWER

  Tuesday, August 11, 2009  9:00 pm

                                








  "It's going to be a great show," say Ron Perry and Rolly Chiasson of the Athena Astronomy Club.  

  Experts at NASA estimate there could easily be one or two every minute at the shower's peak....






  The show begins at 9:00 pm on Tuesday, August 11.  We haven't yet determined the best location to hold the Perseid Party so check back in the coming weeks.    Of course, all this presumes the night skies will be clear.  

  We're also not sure what the fee will be but as soon as we have things finalized, it will be on the site.

  Ron & Rolly will start with an outdoor video presentation explaining what you can expect to see.  The source of the meteor shower is the Comet Swift-Tuttle.  Although the comet is nowhere near Earth, its tail does intersect our orbit.  We glide through it every year in August and tiny bits of comet dust hit Earth's atmosphere travelling 132,000 mph.  At that speed even a smidgen of dust makes a vivid streak of light....a meteor...when it disintegrates.  Because Swift-Tuttle's meteors fly out of the constellation Perseus, they are called "Perseids."






  While the first meteors should be visible around 10:00 pm, as the night unfolds, Perseus will climb higher into the sky and the meteor rate will increase significantly.  By 2:00 am dozens of Perseids may be flitting across the sky every hour....so make sure you prepare for a great time.

  And there's a bonus.  Mars!  In the constellation Taurus, just below Perseus, Mars shines like a bright red star.  Many of the Perseids will flit right past Mars and you may have a hard time taking your eyes off Mars.  There's something bewitching about it....maybe the red colour or the fact that it doesn't twinkle like a true star.  You stare at Mars and it stares right back!

  Rolly, Ron and other members of the Athena Astronomy Club will be on hand with telescopes and binoculars.

  Bring your lawn chairs or folding loungers, warm clothes, bug spray, snacks and refreshments

  If you want to be advised when we have the details finalized....click on BOOK NOW and send us an email.
