Orionids

There will a Meteor Shower on 20th to 22nd of October this year, although you can see it between 15th October to the 29th.

The Orionids are a meteor shower that occurs throughout October into early November. At its peak around October 21-22, as many as 60 meteors per hour can be seen appearing to originate from the radiant located in the constellation Orion near its border with Gemini. Unlike some showers, Orionids can be seen several days before and after the peak night of October 21-22 (at a frequency of approximately 5-10 per hour).

Where to look: As the name suggested, the Orionids refers to the Orion. Although another meteor shower, the Orion meteor, happens around the same period, it can be distinguish from Orionids meteor shower by comparing speed which is relatively faster and if you trace it back mentally, you will see you looking at directly the Orion.

Thus, to locate the meteor shower properly, for us, it will first be looking at the North-Eastern sky, locate Orion and Sirius. Now form a line between Orion and Sirius the source of the meteor will be quite near the horizon under Orion. The meteor shower is unique as it appered in a radiance manner which means you can see meteors shooting out 360 degrees.

Another important fact is that the parent body of Orionids is the Halley comet which we came to know and love and can be seen only once every 76 years.

So, as we all knows that Singapore is surrounded by HDB estates, you can join us at Marine Parade Community Club for a whole night of star gazing.
