Open Council meetings. Now that we have a smaller Council, we should make more effort to advertise the meetings to the entire membership – and possibly lay the foundation for more recruitment to leadership.
Closer ties to UVic. I often hear that members want to get back to meeting at the University. I also think we should offer programs that encourage undergrad students to be active in the RASC-VC.
Closer ties with the FDAO. We have overlapping mandates and volunteer bases. Closer coordination will benefit both organizations.
More in-person events, especially under the night sky.
More scheduled and ad hoc evenings at the VCO
More diversity in membership and leadership.
A budget!

Gates will open at 2pm on Friday. Camp on the field, setup your telescope and bring binoculars to enjoy observing the night sky from a dark site.
Cost: Free of charge for drop-ins!Suggested donation of $20/Adult observers who camp overnight (cash only) – one night or two. Kids camp free.
Everyone who is present is entitled to tickets for door prizes, can attend planned activities and have access to the observing field. Prizes include a telescope!
Star Party Poster – please print it, stick it on your fridge and share with friends! PDFs: 8.5″x11″ & 11″x17″
Don’t want to camp? No problem…it’s no more than a 20-minute drive from most areas of the Cowichan Valley, and only a 45-minute drive from Victoria. Live out of town? Stay in one of the many guest houses, hotels and motels in the Cowichan Valley, however reserve early, since accommodation fills up during the summer.
Staying after dark? Please bring a red light with you – do not use white lights, including cellphone flashes!
Come observe the stars and the Perseid meteor shower from this dark site in the Cowichan Valley. Lots of amateur astronomers will be there to talk about astronomy and to help you observe celestial objects after dark. Observe the Sun (safely) during the day, and hike the trails, swim, play, and enjoy this natural treasure of a regional park. Two days/nights on the weekend – Friday Aug 11th starting at 2PM, all day and evening on Saturday Aug 12th. Camp overnight (1 night or 2), or just drop in for an evening of fun and fascination. A free event, but campers will be asked for a donation if staying overnight.

Seeing is believing: capturing images of nearby solar systems – William Thompson
Astronomers have now discovered over five thousand planets around other stars, ranging from scorching hot Jupiters, to puffy mini-Neptunes, and rocky worlds devoid of atmospheres. Now that we know planets are common, the next step is to learn more about them and compare them with our solar system.
In this talk, I will show how we can take pictures of nearby planets and present the latest developments in the quest to image planets just like our own.
William Thompson is an astronomy PhD candidate at the University of Victoria and an exoplanet hunter. He uses the techniques of direct imaging, radial velocity, and astrometric motion to find and photograph young giant planets, and to study their orbits. William will be joining the National Research Council this fall as a Herzberg Instrument Science Fellow, where he will continue to work on astronomical instrumentation and observational projects.

Probing the Universe with Type Ia Supernovae: legacy and future – Melissa Amenouche
Type Ia Supernovae (SNeIa) are very luminous explosive events in the sky. They can be detected in very remote galaxies and are excellent distance indicators. In the late 90s, the accelerated expansion of the Universe was discovered using the measurements of SNeIa, revealing for the first time the existence of Dark Energy. Today, one of the main goals of modern cosmology is to understand its nature using SNeIa measurements combined with other cosmological probes.
In the past two decades, the number of SNeIa has drastically increased along with our understanding of these objects and their ability to indicate distances. And this will continue with the current and new generation of surveys like the Zwicky Transient Facility (ZTF) and the Large Survey of Space and Time (LSST). I will review the ongoing efforts to unlock precise cosmological measurements with ZTF samples, many of which can be extended to LSST data, with a focus on key steps of the analysis.
Melissa completed her PhD in December 2022 in France. She is currently a postdoc fellow at NRC-Herzburg Astronomy and Astrophysics Research Centre involved in a new Canadian spatial telescope (CASTOR). She is also calibrating and simulating Type Ia Supernovae data from the Zwicky Transient Facility (a great telescope in California) to help answer key questions about our understanding of the Universe and its evolution.
Sunday Aug 13th
Cleanup – everyone please pitch-in & help
12:00 pm – departures by Noon please!
The Island Star Party is hosted by the Royal Astronomical Society of Canada, Victoria Centre, with support from the Cowichan Valley Starfinders.
Directions to the star party
Head west off the Trans-Canada Highway on Koksilah Road and turn right onto Tigwell Road. The park is at the end of the road. If you are driving a big vehicle, we suggest you turn west off the Trans-Canada Highway at Allenby Road, then turn left onto Koksilah Road and left onto Tigwell Road. This slightly longer route will avoid a low-clearance rail bridge on the more direct route.
Bright Angel Park, 4528 Tigwell Rd, Cowichan Station, BC
Lat 48° 44.0246′ N, Long 123° 40.5144’W
What to expect
Dark sky and red lights on the observing field
The night sky at this location is very dark, but there is a light dome to the north from the City of Duncan. Views in the other directions and overhead are excellent, and at this time of year Sagittarius is visible in the early part of the evening to the southwest.
There is limited camping on the observing field with your tent and car where telescopes and other astronomy gear can be set up. There is some power on the field for astronomy equipment and to charge small devices. Please do NOT park on the field with your vehicle if you plan to leave after dark! In this case, move your vehicle off the field after setting up, and park outside the gate on Tigwell Road with your headlights facing away from the field. The same parking request applies to visitors for the evening – park outside the gate and walk into the field.
Washrooms are a short walk from the observing field with sinks, toilets and urinals, but no showers. Red lights will mark the way at night along the forest trail.
Playground and workout gym on the observing field
Park gates are open from 7am – 9pm daily. Make sure your vehicle is outside the gates before 9PM if you plan to leave later on!
Explore the trails through the forest and along the Koksilah River – a nice way to spend the day. Good swimming too, although the river water is cold!
Pets are allowed in the park and at the star party, but must be under effective control of their owners at all times. If your dog knocks over an expensive telescope, you just bought it!
Drinking alcohol or smoking is not allowed in public areas of the park.
Trailers and motorhomes are not allowed in this regional park.
Dry summer conditions demand that no open flame be used. Please cook using a camp stove in the Picnic Shelter by the lower parking lot. No campfires or open flame please!
Although the observing field is flat, it is bumpy, so people with mobility issues may find some areas are not easy to navigate. The washrooms are accessible by using the trail through the forest and navigating a modest slope.
What’s nearby
Tim Horton’s fast food dine-in and drive-thru and a Co-op gas station and convenience store are both nearby at Bench Road and the Trans-Canada Highway.
Big box stores, grocery stores and malls are a short drive away in Duncan, Cobble Hill and Mill Bay.
Pizza and other fast food can be ordered from and/or picked up at numerous local establishments.
Espresso drinks and other fancy beverages are available in Duncan, Cowichan Bay, Cobble Hill and Mill Bay.
Whippletree Junction – a variety of eclectic stores that are worth a visit, located nearby on the highway.
The fascinating and historic Kinsol Trestle is a short drive from the park, where the Trans-Canada Trail crosses the Koksilah River. The trestle is an easy walk from the parking lot – level and accessible.
Wineries in the area are too numerous to mention individually! Look here: Wine Festival Specials
BC Forest Discovery Centre – steam trains, historic forestry equipment and local history – fun for all ages

February 26, 2023
Good day to everyone. The Board of Directors of the Society is providing this update to the membership concerning decisions that have been made after consultation with the National Council and with the Centres through a poll that was conducted in the last two weeks, as well as changes to head office staff.
First, SkyNews: As the membership knows, for many years SkyNews magazine has published by SkyNews Inc., which is an Ontario business corporation. Nine years ago the RASC acquired SkyNews Inc. from its previous owners, and SkyNews Inc. thereupon became a wholly-owned subsidiary corporation of the RASC. SkyNews Inc. has its own board of directors, who are appointed by the RASC through the Society’s Board of Directors. The SkyNews board makes all decisions concerning the business and affairs of SkyNews Inc.
SkyNews astronomy magazine
SkyNews has lost money in four of the nine years of the Society’s ownership. Disregarding the one-time $60,000 COVID relief grant that SkyNews received in the 202-21 financial year (two-thirds of which has to be repaid this year), on average SkyNews has lost more than $10,000 per year during this nine-year period. The losses are increasing. The average loss in the last five years has been more than $25,000, and the loss for the current financial year, which ends on March 31, will be on the order of $50,000. These losses have to be financed by the shareholder, the RASC, which therefore effectively costs each member more than $10, and also endangers the RASC’s charitable status. As is the case with so many periodicals in North America, the SkyNews subscriber base has diminished sharply, from about 20,000 nine years ago, to 6-7,000 today. Advertising revenue has also declined dramatically, to less than one-third of the level when the Society acquired SkyNews.
As a result, SkyNews is no longer sustainable. After numerous meetings and discussions over the last few weeks, and consideration whether SkyNews could be saved in any form (including digital only), the Society’s Finance Committee and Board of Directors therefore concluded that SkyNews Inc. should cease all operations, including publication of the magazine. A majority of the Centres who responded to the poll agreed. Last week, therefore, the board of directors of SkyNews Inc. passed a resolution implementing the RASC Board’s recommendation, with the result that SkyNews will be shutting down. The SkyNews Inc. board will be meeting this coming week with legal counsel to start the shutdown process. The Editorial Board of the Society will be considering whether in future some of the content that has previously appeared in the SkyNews magazine can be incorporated into the RASC’s other publications, such as the Journal.
Second, the robotic telescope: The RASC board has also decided, again after consultation with the National Council and the Centres, to divest the Society of the robotic telescope, which is also a money-losing operations.
Third, head office: One of the important areas in which the Society can reduce expenses is with the number of head office staff. Some staff have been let go, and two others have resigned. This included Executive Director Phil Groff, who has been with the RASC since the fall of 2019 and has now found a position that is more in line with his previous training and experience. We wish Phil all the best with his future endeavours. While the Board conducts a search for a new Executive directors in the coming period, we are fortunate that former Executive Director Randy Atwood has agreed to step in as acting E.D. for the next few months. Randy has been a member of the Society since the 1970s, is a former President of the Society and an RASC Fellow, and has detailed knowledge of the operations of both head office and the Society as a whole.
The Board intends to communicate regularly with the membership about additional decisions that will be taken to place the Society on a more stable financial and operational footing.
Henrietta Leavitt discovered the Type 1 Cepheid Variables, correlation between the brightness and variations in the luminosity
Leavitt’s discovery used by Edwin Hubble, who in 1923 settled the Shapely-Curtis debate. The Hubble Law related distance to velocity (red shift), the start of cosmology as we now know it.
