The Orionids can be seen over a large area of the sky.
Orionids are an annual meteor shower that lasts approximately one week in late October.
In some years, meteors may occur at rates of 50–70 per hour.
The radiant of the Orionids is located in the south-eastern sky before dawn, as viewed from mid-northern latitudes.
