It was mentioned in one of the questions a couple of weeks ago that it's somewhat more likely to rain in the eastern U.S. on weekends rather than weekdays. However, this is not true if a meteor shower of solar eclipse is forecast to occur during the work week. Of course, even if the sky is clear and the moon was in the new phase, the meteors may be no shows.
Meteors can be sporadic, or they can occur in showers.
Sporadic meteors can be seen on any given night and, though usually faint, they may on occasion be quite brilliant. These unexpected meteors are often vivid in our memory. On any clear night, perhaps a patient observer can see as many as 10 meteors in an hour. They nearly all burn out completely somewhere at altitudes about 25 miles above the surface. Most of the visible meteors vary in size from about that of a grain of sand to that of a watermelon seed or maybe a pea.
