A Month of Eclipses

This month we bid farewell to the constellation Scorpius and quite soon – Sagittarius. Both were the focal point of every star party this past summer. To witness the middle our home galaxy on a moonless night is beyond words. I hope you had the opportunity to see the beauty of the night and all it has to offer. But even though these two are sliding into the southwest skies, all is not lost.

The RASC Board of Directors is pleased to announce the hiring of Executive Director Randy Attwood of Toronto, effective 2014 September 2.

The Summer Triangle – part 2

We now continue our tour of the famous summer triangle. Half way between the Double-Double and Deneb is a dense magnitude 9.5 open cluster identified as NGC 6819. Pretty well any telescope will reveal about 30 stars but larger instruments are required to pick up the many fainter suns. NGC 6819 is located some 7,200 light years and thought to be around 2.3 billion years old.

This information comes from Stan Taylor of the Toronto Centre: 

The use of Green Lasers will be one of the issues discussed at the COPA flight 70 meeting 7:30 Thurs Sept 4 RCAFA 420 Wing, 1000 Stevenson Rd N, Oshawa, ON. RASC members are encouraged to attend.


The Summer Triangle – part 1

The night sky is a collection of patterns known as asterisms which, when connecting the dot (stars) takes on the shape of objects, people, and animals. The larger boundaries of each asterism make up the individual constellations. The summer triangle is the connection of three bright stars from three completely different asterisms. To the far left we have the star named Deneb or the tail of Cygnus the Swan.

The Executive Director manages the daily operations of The Royal Astronomical Society of Canada. This includes activities related to our charitable mandate, publications, and member service. Our current ED, Deborah Thompson has served us well, and has chosen to take a leadership role at another not-for-profit organization in a few weeks’ time. We wish her the best and thank her for nearly four years of service.

The Mighty Hercules

As the sky finally darkens well after 10 p.m. on these summer nights, plan to hunt down some great objects in the constellation Hercules. The mythological son of Zeus is positioned directly overhead and well placed for observing and photography. At first glance, the asterism stars range from magnitude 2.2 to 4.4 and looks like a crooked letter H with its left side kicked in mid way up. These main stars reside from 35 to 408 light years from us. Hercules is the fifth largest constellation in area with 1,225 square degrees of sky.
