   Mark Cash with the University of Texas McDonald Observatory said either way a blue moon is not a common event. He said two full moons occur in the same month about every 33 months.
   
   Cash said the last was in November 2001. The next in North American time zones will be May 2007.
   
   "It's rare because the moon is full every 29.5 days," Cash said. "So, the timing has to be just right to squeeze two full moons into one month."
   
   Cash said the exact origin of the term "blue" moon is difficult to pin down. But he said it likely refers to times when high altitude dust particles from such sources as volcanoes or forest fires gave the moon a bluish color.
   
   He said those are also rare events and people shouldn't expect to see a blue-colored moon this weekend.

   Cash said Nasa officials have said people in Europe and Asia could see as many as 200 meteors per hour. He said the numbers will probably be closer to 40 to 60 per hour in North America.
