Stargazing Calendar for October 2015
On October 8 we will witness the Draconids meteor shower. It is a minor meteor shower producing only about 10 meteors per hour originating from dust grains left behind by comet 21P Giacobini-Zinner, which was first discovered in 1900. The Draconids is an unusual shower in that the best viewing is in the early evening instead of early morning like most other showers.

The series will not be a regular one: I will only write an article after using a complicated astronomy term that some of you would need me to explain. Definition The apparent magnitude (noted as m) of a celestial body is a measure of its brightness as seen by an observer on Earth. Since the apparent brightness…
