Astronomy Day 2024 – event photos

May 19, 2024 – Yesterday the Victoria Centre held a highly successful IAD event at the Royal BC Museum and at the Centre of the Universe. We had big crowds taking in our presentations at the RBCM during the day, and in the evening at the Centre of the Universe.

I want to thank everyone whose great work contributed to this success, notably the volunteer team headed by Randy Enkin, with big assists from Lauri Roche and David Lee, amongst many others. I also want to thank the people at the RBCM, the Friends of the DAO, and the other groups who made Astronomy Day a success.

I also thank the Victoria Times-Colonist, which ran articles on IAD two weeks ago and yesterday, along with photos in today’s newspaper.

You Versus the Universe – Nathan Hellner-Mestelman

Nathan Hellner-Mestelman

Abstract: During our everyday lives, we donít usually think about the mind-boggling scale of the universe around us, the enormous history of our cosmos, and the epic future awaiting us. Prepare to leave our little planet behind on a quirky voyage across time and space!

Bio: Nathan Hellner-Mestelman is an impassioned astronomy nerd in Grade 11, and recent author of Cosmic Wonder: Our Place in the Epic Story of the Universe. He enjoys reciting slam poetry, playing the ukulele, and sharing the wonders of the universe with all.

The Stars – John McDonald

John McDonald

Abstract: When I was a child I was fascinated by the points of light in the sky we call stars. What are they, where did they come from and how far away are they? Are they all like our sun with planets travelling around them and are any of those planets inhabited? In this talk I will tell you some of the fascinating things astronomers have learned about stars.

Bio: John McDonald is a physicist, a Fellow of the Institute of Physics (UK) and Professor Emeritus at the University of Alberta. His research was in particle physics contributing to the work at TRIUMF in Vancouver and CERN in Europe. Currently, John is enjoying retirement in Victoria and having a great time observing and photographing the sky.

North Star to Freedom – Amy Archer

Amy Archer

Abstract: What is the connection between the 100,000 people that traveled the underground railroad and the night sky? Can you imagine the logistics of using stars to guide you over such a far distance, while in immediate peril? Do you want to know how a meteor shower helped connect families of enslaved people that had been separated? From a young age Amy has thought it fascinating how the night sky could be used to navigate a people from unspeakable hardship to freedom.

Join Amy Archer to hear stories about how the night sky played a hand in helping people navigate from unspeakable hardship to freedom. The night sky is full of new discoveries waiting to be had, and there are so many stories to share of its rich history, join us as we explore vignettes about the Underground Railroad and the Night Sky.

Bio: Amy is a first generation Canadian with roots from Trinidad and Tobago, she was born in Edmonton, Alberta and has spent most of her life on the West Coast. Amy is the mother to one very inquisitive teenager, whom she is always learning from. Amy is the Vice-Chair of the Friends of the Dominion Astrophysical Observatory (FDAO) and has been involved with the organization for the last 7 years. Amy is constantly fascinated by the knowledge of the astronomers and can be found at most Saturday Night Star Parties either behind the scenes or looking through her favorite telescope.

Making the Most of Spilled Milk:  The Story of the Milky Way, Our Home Galaxy – Simon Smith

Simon Smith

Abstract: We live in the Milky Way galaxy, a swirling sea of old stars and young stars, bright stars and faint stars, and massive clouds of gas and dust. But where did our stars, gas, and dust come from, and how did they all arrange themselves into the soft glow of light we see splashed across the sky on a crystal clear night? In this presentation, I will share with you our best understanding of how the Milky Way formed from the chaotic early Universe, how it built up all the many stars we see around us, and its likely fate in both the near and far future of the Cosmos.

Bio: Simon is currently working towards his Ph.D. in Astrophysics at the University of Victoria. He studies the smallest galaxies in the Universe – known as ‘Dwarf’ galaxies – and has helped discover several of these tiny galaxies in and around our cosmic neighbourhood. Originally from the small town of Oxenden, Ontario, Simon has lived in Victoria for three years and has been a keen participant in the astronomy outreach community.

The Photographic Legacy of the DAO and John Stanley Plaskett – Dennis Crabtree

Posted by as UVic Meetings

Date/Time: Wednesday May 8, 2024 starting at 7:30PM

Location: University of Victoria, Bob Wright Centre, Lecture Theatre A104. Park in Lot 1 (pay parking) and cross Ring Road.

Transcript video of meeting presentation

The Dominion Astrophysical Observatory (DAO) is fortunate that John Stanley Plaskett arranged to have the construction of the Plaskett telescope photographically documented. There are approximately 150 8” x 10” glass plates that were taken during the construction. I am in the process of scanning these plates at high resolution and then “cleaning” them in Photoshop.

About three years ago, I discovered a collection of negatives and prints that were taken by John Stanley Plaskett during the period from 1910 to 1914. These images were taken in Pasadena, Wakefield Quebec, England, Germany, and Victoria.

I will show a selection of images from both of these important historical collections. There will also be a surprise show and tell.

Dennis Crabtree

We are fortunate to have Dennis Crabtree join us to do a presentation about the photographic legacy of Victoria’s Dominion Astrophysical Observatory (DAO) and John Stanley Plaskett. Dennis Crabtree is a retired astronomer who worked for the DAO for over 35 years, being a former Director of the Observatory. During his career he worked for the Canada-France-Telescope, the Gemini Observatory and at the Space Telescope Science Institute. He is the unofficial historian of the DAO.

President’s Message – April 2024

Posted by as President's Message

What else can I write about or even talk about other than that celestial event that took place on April 8?

I had seen the 1979 eclipse in Manitoba and the 2017 eclipse in Oregon. After 2017, all us eclipse addicts faced a difficult decision: where should we go to see the 2024 total solar eclipse? The decision wasn’t simple because of the path of this eclipse and the fact that April weather is more problematical than the August weather conditions in 2017.

In part because of the pandemic, I didn’t make arrangements for the eclipse years in advance as I had done for 2017. As 2024 dawned, I concluded it was too late to arrange a trip to Mexico or Texas for a reasonable price. I know many people in Toronto, but I felt that too many people chasing the eclipse in Hamilton and environs might complicate things. So I decided to go to Windsor, Ontario, just outside the path of totality. We have relatives there, and it would be relatively easy to cross the border there to chase the eclipse in Ohio if necessary. But it was still a big gamble, and I made sure I had other things to do to justify the trip.

As April 8 got closer, weather predictions called for clouds in southern Ontario, and when I arrived in Toronto on April 4, I was greeted with cold, cloudy and rainy weather. Two days before the eclipse as Audrey and I made our way to Windsor, the skies cleared. Things were looking more promising, but clouds were still predicted for the eclipse.

The night before, the prediction was still more promising for Ohio than the Windsor area, and Ohio locations were closer to the centreline of the eclipse, which promised a longer period of totality. I prepared to cross the border.

April 8 dawned in Windsor with blue skies. The forecast still called for clouds in the mid afternoon, when the eclipse was due to take place. The forecasts for Ohio called for longer periods of cloudiness in the afternoon, which I feared meant thicker clouds, and so I decided to stay in Canada.

Audrey and I, along with her sister and her husband, drove south from Windsor through Amherstberg into the path of totality. Many eclipse chasers in the area were already arriving in Point Pelee Park, which was closer to the centreline but involved very limited access, so I thought we might set up in Leamington. Before we got there, we found a great spot to watch the eclipse at Colchester Harbour and Beach. The RASC Windsor Centre had set up tents and telescopes there, a restaurant, coffee shop and other facilities were nearby, and scores of people were already settling in to watch the eclipse over Lake Erie.

Looking south across Lake Erie, we saw a bank of clouds that everyone hoped would stay where it was. But true to the prediction, the clouds moved our way and covered the sun as the partial phase of the eclipse began a little before 1 p.m. Fortunately, the clouds weren’t very thick.

Finally, at about 3:12 p.m., totality began. We were amongst the first to see totality that day from Canadian soil. The transition from needing eclipse glasses to full totality with the naked eye seemed to be prolonged to me, but finally we got our 90 seconds of totality and dark skies. Venus was plainly visible through the thin layer of cloud, but I don’t recall seeing Jupiter or any other celestial object. The incandescent but not overpowering glow of the Sun’s corona took centre stage.

In the moments before and after totality, the lighting of the area took on a strange hue. During totality, my viewpoint overlooking Lake Erie allowed me to see the approaching “sunset” to the west and the receding “sunrise” to the east. During this time, I took a couple of photos of the sun and of the light effects around the horizon with my iPhone, and I set up my iPad to film totality. I wanted to spend most of totality enjoying the view rather than messing with cameras.

All too soon, totality was over, and soon people started to leave. We remained for most of the rest of the eclipse to savour the incredible spectacle. By the time we got back to Windsor, all the clouds had disappeared. So had the crowds, and as a result we encountered no traffic jams.

The hours and days that followed became a gigantic debrief on this event. Who got a good view of the eclipse? Who got skunked by the weather? The evening of April 8 I joined many of you in an online Astronomy Café.

It turned out that Joe Carr, John McDonald and Bill Weir got a great look at the eclipse from their cruise ship, The Discovery Princess, and the poor weather in Texas inspired Leslie Welsh to stop in Arkansas to catch the eclipse. Thicker clouds in the Niagara region obscured the eclipse for Jill Sinkwich and Lauri Roche. Marje Welchframe saw parts of the eclipse through clouds in Kingston. The weather was much better in the Montreal area, to the delight of Randy Enkin, Chris Purse, and Brian and Nathan Hellner-Mestelman. Alex Schmid had clear skies in Sherbrooke. The clouds parted for Clayton Uyeda in New Brunswick.

Victoria Centre members’ photos of the 2024 Total Solar Eclipse.

Back in Victoria, David Lee, Kirsten Pedersen and others entertained a good crowd at a rainy Centre of the Universe during the partial solar eclipse here.

Before I came home, I heard about RASC Executive Director Jenna Hinds’ successful eclipse trip to Illinois. A few days later I attended a meeting of the RASC Mississauga Centre in person, and I heard about more experiences along the path of totality, including the troubled weather in Texas, which also affected our good friend Peter Jedicke from the London Centre.

So the viewing conditions for the 2024 total solar eclipse turned out to be less than perfect but better than most of us could have hoped for.

Now the question arises – when is the next one? August 12, 2026, in Greenland, Iceland and Spain. In North America, the wait will go on until August 23, 2044. How long will our waits go on? Those decisions are for another time.
