Don't sleep on Tuesday night , November 17. A couple of hours after the witching hour 2.10 am, to be precise--an army of meteors will come crashing into the earth's orbit and blaze off an two-hour-long magnificent pyrotechnic display, the kind you've never witnessed before. A celestial Diwali, if you please. In 1966, people in North America were treated to a similar display, and now 33 years later-- the return of the cosmic invaders--east and south Asia are the privileged vantage points, Next November, it's the turn of the East Europeans.
