2015 Orionid meteor shower peaks on October 21 – 22


Every October, stargazers all over the planet look forward to the annual Orionid meteor shower. The Orionids are popular because they are one of the two meteor showers created from the debris field of the extremely popular Halley's comet. The annual Eta Aquarids meteor shower in May being the second one. The Orionid meteor shower is not the strongest but it is considered one of the most beautiful meteor showers of the year. 

The Orionids in 2015

The Orionids are so named as the shooting stars seemingly originate in the constellation Orion. In 2015, their visibility is expected to pickup after nightfall on October 20 with the Orionid meteor maximum occurring between the predawn hours of October 21 – 22. At its peak, the Orionid shower will dazzle the night sky with approximately 20 meteors being visible every hour.

Where to view the Orionid meteor shower

The Orionid meteor shower seems to radiate from the constellation Orion. Hence the best time to view the shower is when the radiant point (Orion) is visible over the eastern horizon. Generally, the visibility of any meteor shower is inversely proportional to the brightness of the moon. But since we have a first quarter moon setting by midnight on October 21 – 22, the pre dawn hours when the Orionid shower peaks will be largely moonless and dark. This will make the Orionid meteor shower very clearly visible in both the northern and southern hemispheres.

How to view the Orionid meteor shower

The best way to watch the Orionid meteor shower would be to head to the country side or any place which is free of light pollution. Use a comfortable reclining chair and observe the night sky. It would take an at least an hour to view the shower effectively as most meteor showers follow a spurt and ebb routine and it takes some time for your eyes to adjust to the darkness. 

However, If you have cloudy skies in your part of the world or you basically want to view the Orionid meteor shower indoors then you can check out Slooh's live broadcast of the meteor shower starting October 22, 2015, 00:00 UTC. Slooh is a community observatory that has connected telescopes to the Internet for public use.
