Experts say a bright waning moon may make it difficult to spot early Monday. The Orionids — one of two annual meteor showers from Halley’s comet — can be unpredictable. They can shine like a fireworks display in some years, but can be fairly slow in other years. This highly variable shower may result in anywhere from 20 to 60 visible meteors per hour under ideal viewing conditions. Multiple meteor showers occur annually and you don’t need special equipment to see them. Most meteor showers originate from the debris of comets.
