1. An exceptional year for the Quadrantids
On the morning of Jan. 4, a strong display of Quadrantid meteors is likely for Europe and North America. In the United States and Canada, eastern observers are favored;maximum activity is expected at about 5 a.m. EST (1000 GMT), when the radiant of the shower, located in the constellation Boötes, will be well up in the dark northeastern sky. At the greatest activity level, more than 100 shower members per hour will be visible. However, the Quadrantids influx is sharply peaked; six hours before and after maximum, these blue meteors appear at only a quarter their highest rates.
