Major Astronomical Events

 
1) Orionids meteor shower
 

Fig. 1: Origin of Orionids on the night of 21st

Creating the Orionids meteor shower is the dust grains left behind by comet Halley. Running every year since the ancient times, the Orionids starts from the 2nd of October to the 7th of November. This year, it is peaking on the 21st of October and would produce an average of 10-20 fast meteors per hour with the maximum at 25. However from Singapore, the radiant of the shower this year will be 5° above the eastern horizon meaning that prospects of viewing will be heavily reduced. The moon’s glare would also cover some of the fainter meteors and make viewing even more limited. The meteors could be anywhere in the sky though it originates from the constellation orion. Viewing in a dark location would be best recommended.
 
2) Uranus at opposition

Uranus will be at its brightest of the whole year on the 24th of october, well placed in the constellation Aries for observation. Opposition of a planet occurs when the planet is almost directly opposite the sun. Uranus will also be at its perigee right after opposition and would be at its closest to earth. Best time for viewing would be at 00:49 thought the planet rises from 20:12 to 05:23. It is impossible to distinguish Uranus from a normal blue-green dot unless with the aid of a telescope.

What's up in the Sky?

 

 
Overhead this month is Deneb, part of the Summer Triangle. It consists of Deneb, Altair and Vega, which are widely known recognized in the Chinese love story of Qi Xi (七夕) or the Cowherd and the Weaver Girl (牛郎织女).

Cygnus, the Swan, is a bright constellation and can be found in the northern part of the sky. The bright star at the end of Cygnus, is Deneb, which forms one end of the Summer Triangle and is the easiest way to find Cygnus in the night sky. Albireo, or Beta Cygni, is a celebrated binary star for its contrasting hues, with a brighter orange-hued giant star and a dimmer blue-green hued star

To the left of Cygnus is Aquila, the Eagle, also a decently bright constellation with a bright star, Altair. Lastly, Lyra is a somewhat bright constellation with Vega being particularly bright

In the vicinity of the Summer Triangle, there are quite a number of fairly bright deep sky objects that can be found. Firstly, the Coathanger asterism (Brocchi’s Cluster) can be found by tracing a line towards Vega from Altair. By tracing a line from Vega through Rukh, one can find the open clusters Messier 39, Caldwell 16 and Collinder 456 (NGC 7686).

Thereafter, one can trace a line towards Deneb from Albireo, finding the open cluster NGC 6871, as well as the reflection nebula IC 5076 (reflecting Deneb's starlight). From Sadr, tracing a line through Deneb, one can find the Elephant’s Trunk Nebula, a nebula rife with young stars and part of the larger IC 1396 nebula complex.

Moreover, one can find NGC 6940, an open cluster, by tracing a line from Gienah towards Altair, and afterwards the fairly rich open clusters Graff’s Cluster (IC 4756) and NGC 6633 by tracing a line from Theta Aquilae (θ Aql) through Deneb Okab. Lastly, one can find M15, a fairly bright globular cluster by tracing a line from Biham to Enif.
