As my term as centre president draws to a close, I thought I would look back at some of the noteworthy events from the past 2 years.

• Centre member Brenda Stuart provided the illustrations for the new edition of the RASC publication Explore the Universe Guide.
• We had longer seasons of the Summer Star Parties at the DAO in both 2017 and 2018. These started with Astronomy Day at the Royal BC Museum. The stat parties continued to be well attended.
• Centre member Terry Ryals volunteered his carpentry skills to build a security cabinet so we could install our new monitor in the portable where we hold Astro Café.
• Victoria High School proposed and launched an Astronomy 11 course.
• In partnership with Parks Canada, observing evenings were held at Fort Rodd Hill and Gulf Islands National Park.
• Members who had remained in Victoria hosted public eclipse viewing for the solar eclipse on August 21, 2017. Many members travelled to the US to see the total eclipse.
• The centre purchased a new telescope for the VCO and sold the surplus equipment.
• In 2018, RASC celebrated its sesquicentennial with a number of special events, a commemorative Royal Canadian Mint coin, and a pair of commemorative stamps issued by Canada Post.
• Centre members Lauri Roche and Jim Hesser organized and coordinated a national contest in honour of the sesquicentennial called Imagining the Skies.
• The centenary of the Plaskett Telescope was celebrated on May 3, 2018 with the National Historic Site plaque unveiled.
• RASC members were invited to attend sessions at the Canadian Astronomical Society annual meeting held in Victoria during May 2018.
• Centre member Chris Gainor was elected National President at the 2018 General Assembly.
• Centre members David Lee, John McDonald, and Jim Hesser assisted with a second concert of the music of William Hershell. The event in November 2018 was supported by a grant from the RASC special projects fund.
• David Lee and Dan Posey offered a workshop on PixInsight to a group of astrophotography enthusiasts.
• Astro Café continues to be well attended and our monitor is well used.
• Centre members continue to volunteer countless hours for the schools program, Vancouver Island Regional Science Fair, and other outreach events.

I have enjoyed my term as president. It has been my honour to serve the centre and I thank all our members for their contributions. It has been a great experience to work with such an enthusiastic group of people and I look forward to my next role as past president.

A reminder that this month’s meeting is our Annual General Meeting that will take place on Saturday, November 17 at the Cedar Hill Golf Club with doors opening at 6 p.m. The evening starts with a dinner so if you have not booked a seat please do so by Sunday, November 11. The meal costs $40 and is a buffet with a pre-selected entrée. The entrée choices are chicken, salmon, steak, or vegetarian ravioli. If you wish to attend, send me your entrée selection at president@victoria.rasc.ca. Please see below for more information. If you cannot attend the dinner, the speaker and meeting portion are open to everyone at no charge.

Due to exams at the University, our monthly meeting on Wednesday, December 12 will be held in the Engineering and Computer Science (ECS) building room 116. This is near the room where the June 2018 meeting was held.

A final note and a concern. Our centre is not alone in having issues finding members willing to put their names forward for the leadership positions. We rely on a group of members to coordinate activities, make decisions, and keep the centre running in accordance with the relevant regulations. Despite a membership over 270, nominations have not been forthcoming for the incoming centre executive and this is a major problem. The centre cannot run without the council members. If we do not have leaders the centre is not viable and we really must question if we can continue to exist. That would be a sad occurrence after a history of 104 years. So, this is a final appeal before the AGM. We do need some more nominees for people to lead the centre.

This month, I am starting with thanks for contributions to our centre.

My first thanks go to the Astro Café hosting team, Reg Dunkley, Barbara Lane, Kurt Lane, and John McDonald. Their efforts to get the room set up, coordinate presentations, and keep us fed with coffee and cookies are appreciated. Attendance at Astro Café has remained high throughout the year and I attribute that to the work of this team. In addition, I would like to thank everyone who has presented at Astro Café this year. It is impressive to have our youngest member making presentations as well as a number of new members. Well done everyone and I look forward to the resumption of Astro Café on Monday, September 10.

Nelson Walker also deserves thanks for two contributions. Nelson has taken on the modernization of our centre by-laws required by amendments to the BC legislation that governs societies. He has worked tirelessly on this document and we will be distributing the draft to members for discussion and feedback soon. Our plan is to hold a vote on adopting the new by-laws at the monthly meeting on Wednesday, September 12. In addition, Nelson brought a number of his surplus items to sell at Astro Café on May 28. He donated the proceeds to the centre’s public outreach fund. He had a great selection of gear and sold most of it. Over $400 was raised via his generosity. Thank you for those contributions, Nelson, they are greatly appreciated!

Another piece of good news is that the remaining items from the VCO have been sold. Thank you to the team members who worked on that project. I am sure the new owners will put that equipment to good use.

Later this year, we will be seeking nominations for positions on the council. Although that is some time in the future, I want to highlight this now as being on council is a great opportunity to become more involved in the centre and its operation. We rely on members who are willing to devote some of their time to the administration tasks. As you will see in the by-laws, there are some defined positions augmented by members who assist with specific tasks. The time commitment is not too onerous; the adage many hands make light work is true. In addition to the centre activities in which you normally participate, there are council meetings every second month, some duties specific to the role that need to be done on a regular basis, and occasional emails needing a response. I hope that some of members who have not previously served on council will consider it this year.

Finally, please remember that our June monthly meeting is in a different room. We will meet in the Engineering and Computer Science building room 124 for our Wednesday, June 13 meeting. As we do not have monthly meetings in July and August, our next monthly meeting will be on Wednesday, September 12.

Have an enjoyable summer!

May has started with an incredible celebration. The Plaskett Telescope turns 100 this month and the plaque designating the DAO as a National Historic Site of Canada has been unveiled. I was asked to speak on behalf of the Centre at this event. Here is a summary of the speech I made.

In addition to the centenary of the Dominion Astrophysical Observatory, 2018 marks the sesquicentennial of the Royal Astronomical Society of Canada or RASC. Founded in Toronto by a group of astronomy enthusiasts, RASC has grown to be a national, coast to coast organization. With the addition of the Yukon Centre in 2016, the society is moving toward becoming truly coast to coast to coast.

The Victoria Centre joined the Royal Astronomical Society of Canada in 1914. Centre historians have discovered that the 1914 founding was not the first attempt by astronomy enthusiasts in Victoria to join RASC. In 1909, efforts were made to start a centre here which were unsuccessful.  However, just five years later, the effort was successful. Why was that?

I think a critical piece that was missing in Victoria of 1909 was an anchor for an astronomy group.  In the pre-information age, the success of societies such as RASC was greatly increased when there were locally available, high quality resources to support the efforts of the amateur members. Typically, this would be a research university. A university would provide faculty and staff members who might have expertise in astronomy, current publications in the library, and, perhaps most importantly, access to high quality equipment. By 1914, what had been missing in Victoria was starting to take shape.

The selection of Victoria as the home of the Dominion Astrophysical Observatory meant that Victoria became the centre of astronomy in Canada. Having a top notch research institution is the best possible support a RASC centre could hope for. Just look at the telescope that came with this observatory! No one else had anything like that. As a result, the location of the DAO in Victoria was instrumental in the founding and success of the Victoria Centre. It is likely that Victoria would not have a 104 year old RASC centre had this observatory been built somewhere else.

A particular strength of the DAO continues to be public outreach. From the very early days, the public were welcomed to look through the telescope. A centre member studying its history discovered that the DAO was a leading tourist attraction in Victoria of the 1920s; records show that more than 30,000 visitors per year came to the hill. If you ask almost anyone who grew up in Victoria, they can describe a visit to the observatory so this facility certainly made an impression. For 100 years, it has been part of the fabric that makes Victoria an outstanding place to live.

Our centre benefits greatly from our relationship with the Dominion Astrophysical Observatory. From the employees who are active RASC members to the many who volunteer to speak at our monthly meetings, we are a stronger centre because of the Dominion Astrophysical Observatory. In addition, the Victoria Centre has a larger membership that many other centres in Canada that have greater surrounding populations. I attribute some of that to the interest in astronomy that is generated by the presence of the Dominion Astrophysical Observatory.

Our tech committee has made further progress with the upgrade to the Victoria Centre Observatory telescope. More equipment has arrived and has necessitated the installation of some different wiring in the mount. Recently, members of the committee held a work party at the VCO to make the changes.

The committee has also prepared the surplus equipment for sale. Please see victoria.rasc.ca/for-sale-observatory-equipment/ for the details of the items for sale and how to make an offer to purchase. The sale is open for the month of April. This is another step forward in the project as realized funds will be used for further purchases of equipment for the VCO.

Late last month, a few of the council members received emails from what appeared to be the president’s address. These emails asked the recipient to make an urgent payment on behalf of the centre using personal funds; a promise was made that these funds would be reimbursed by the centre within short order. This was a scam. It does go to show that the criminal element is out there looking for opportunities to defraud anyone. I mention this as a reminder to all of us to remain vigilant any time we are asked for money by email.

Here are some announcements:

RASC members may register to attend the CASCA 2018 conference that takes place May 22 – 26. See casca2018.ca/ for more information.

The Friends of the Dominion Astrophysical Observatory has launched a new website. The new URL is www.thecentreoftheuniverse.net. This is where the information about the Summer Star Parties will be posted.

The Vancouver Island Regional Science Fair is taking place on April 8 and 9 in the Elliott Building Lecture Wing at the University of Victoria. See web.uvic.ca/~virsf/index.php for more information.

Our monthly meeting on Wednesday, April 11 at 7:30 p.m. will be in the Elliott Building, room 167, as our regular room is being used for an exam.

The Science and Technology Awareness Network (STAN) helps promote science and technology education. This year, their conference is on Wednesday, April 11 in Vancouver. The conference web page provides registration and all other details, www.stanrsst.ca/stan-conference. By the way, STAN membership is free; you may be interested in joining STAN especially if you have an interest in science and technology education.

Astronomy Day will take place on Saturday, April 21. The daytime portion will be at the Royal BC Museum and the evening will be the first of the summer star parties at the DAO.  If you are not already on the list to volunteer at those events please let Ken, our outreach coordinator, know that you are available. He may be contacted at outreach@victoria.rasc.ca.

As the spring and summer approaches, planning is underway for our annual season of outreach events. The first event of the season is Astronomy Day on Saturday, April 21 at the Royal BC Museum. We will require volunteers to help with this event including people for the information table, people to do a show and tell with telescopes and their astrophotography, and some solar viewing as well if the skies cooperate. If you have not already been contacted and wish to help out, please contact Ken (outreach@victoria.rasc.ca) to put your name on the list as an outreach volunteer.

We will be holding another season of Star Parties at the Dominion Astrophysical Observatory on Saturday evenings. The first of these evenings will be on Astronomy Day. The season will continue until Saturday, September 1 for a total of twenty evenings. Planning is underway for some special evenings including Saturday, May 5 to coincide with the 100^th anniversary of first light of the Plaskett Telescope that was on May 6, 1918. Again we will need people to be on hand to direct the visitors, provide views of the sky with telescopes, and other duties. We have a contact list of volunteers but if you are not on the list already and would like to be added please contact Chris (president@victoria.rasc.ca).

The annual general meeting of the Canadian Astronomical Society (CASCA) is taking place in Victoria this year. The conference title is A New Century for Canadian Astrophysics and it will be at the convention centre from May 22 to 26. Through a special arrangement with the organizing committee, members of RASC may register to attend. The options for RASC members are a one day rate or four day rate; the early bird rates are in effect until April 6. Complete details about the meeting, including a list of invited, centenary, and education and public outreach speakers, an outline of the graduate student workshop program, and special events, can be found on the CASCA 2018 website. One of the speakers, former RASC president R. Peter Broughton, is the author of new book about John Stanley Plaskett founder of the Dominion Astrophysical Observatory. Entitled Northern Star J.S. Plaskett, it is now available from the RASC store.

I find it fascinating that we have developed a sensationalized vocabulary about naturally occurring events. Perhaps it is the result of reality television becoming so prevalent that everything must be a challenge, a contest, the best, the brightest, the most shocking, etc. Having the recent lunar eclipse labelled with 3 different descriptors, super moon, blue moon, and blood moon, made for some interesting headlines. Are these events really deserving of these labels?

The distance between the moon and the earth does change throughout the month due to the moon’s elliptical orbit. For a viewer on earth, the apparent change in the moon’s diameter between apogee and perigee is about 13%. That does make a full moon around the perigee appear larger thus potentially brighter. But do most of us really notice without being told? Probably not. As the earth has a greatly varying atmosphere, which has a significant influence on light transmission, the amount of light from a full moon is not a reliable indicator. How many of us can recognize that a full moon is larger, or smaller, than the previous time we saw it? Photographs will show a difference but most of us do not have that sort of visual memory. Is a moon that appears to be 13% larger than at its smallest apparent diameter a difference worthy of being called a super moon? I lean toward describing it as a full moon near the perigee.

According to sources I have found, the term blue moon, when used to count full moons in a certain time period, was originally used for seasons. Most seasons have three full moons but every tenth season or so has a fourth full moon. The blue moon was the label given to the third full moon of a season with four full moons. Along the way, blue moon has become an accepted expression for the second full moon in a single calendar month. Is having an extra full moon in a month or a season, both of which are arbitrary, human-designated periods of time, significant? Why not just refer to it as the second full moon of January? By the way, March 2018 also has 2 full moons so we will have a second blue moon this year.

The term blood moon is used to describe the red-coloured moon that we see during a lunar eclipse. During the eclipse, the sun’s light is blocked from reaching the moon’s surface directly. The earth’s atmosphere scatters light, particularly in the blue-violet end of the spectrum. This means that light that has passed through the earth’s atmosphere and travels on toward the moon is primarily at the red end of the spectrum. Some of this light will end up reaching the moon’s surface and the result is a moon illuminated by light that is strongly in the red wavelengths. I’m not sure why we just don’t call it a red moon.

So, although we did not see much of the eclipse here, I hope those who did enjoyed seeing the large, red moon caused by the lunar eclipse during the second full moon of January 2018 when the moon was close to perigee. Ok, maybe saying the super blue blood moon sounds better!
