Because the light of most meteors is faint, meteor observations should be made under conditions as dark as possible, away from city lights, and preferably when the Moon's light is absent from the sky. When watching even the best annual showers, however, you need to be patient. You might see one meteor every minute or two on average. And that is under ideal, dark-sky conditions with no moonlight or artificial light pollution. Any skyglow dramatically cuts down the number you will see.
Most meteor showers are active between midnight and dawn.
The sightings of meteors increases toward the morning hours because it is after midnight that an observer's location is aimed in the direction of the Earth's path about the Sun. No matter how the shower performs, the best time to watch is from 2 or 3 a.m. in Singapore until the first light of dawn. Fortunately, in 1998, Leonid watchers face no hindrance from moonlight. In 1999, the waxing gibbous Moon will set after 1 a.m., leaving the crucial predawn hours dark for meteor watching. The best time to watch the Leonid Meteor Shower in Singapore is from 2 a.m. until the first light of dawn on early morning of 18 November 1999.
