RASC VICTORIA CENTRE ANNOUNCES AUGUST 21 ECLIPSE VIEWING IN VICTORIA
Viewing planned for Royal BC Museum, Mount Tolmie & Metchosin Cricket Pitch
Members of the Victoria Centre of the Royal Astronomical Society of Canada will be setting up their solar telescopes in three locations around Greater Victoria for public viewing of the solar eclipse on the morning of Monday August 21.
Because looking directly at the Sun at any time is dangerous without proper protection, the telescopes at these events will be equipped with shielding to allow members of the public to safely see the eclipse. While the eclipse will be total in some parts of the United States, the eclipse in Victoria will be only a partial eclipse, where parts of the Sun will always be visible. The August 21 eclipse in Victoria will begin at 9:08 a.m. and end at 11:38 a.m. At 10:20 a.m., the Moon will block around 90 percent of the Sun as seen from Victoria.
RASC members will be setting up their telescopes during the eclipse on the morning of August 21 in front of the Bell Tower at the Royal B.C. Museum at 675 Belleville Street in Victoria, at the Cricket Pitch in Metchosin behind the Fire Hall at 4400 Happy Valley Road, and at Mount Tolmie Park off Cedar Hill X Road in Saanich, which can be reached by going up Mayfair Drive to the top of the Mountain, where telescopes will be located on the water reservoir facing south.
The University of Victoria will hold an open house for eclipse viewing that morning open to the public at the UVic Observatory on the fifth floor of the Bob Wright Building.
There will be no public eclipse viewing at the Dominion Astrophysical Observatory.
Victoria will experience a 90% solar eclipse on the morning of Monday, August 21, 2017 with the maximum at 10:20 a.m.
IMPORTANT SAFETY INFORMATION: Approved eclipse glasses or approved eclipse filters must be used at ALL times when looking at the sun. Serious and irreversible eye damage may result from looking at the sun without approved safety equipment.
Here are the public viewing sites in the Capital Region that have been identified:
Mount Tolmie Park – RASC members will be at the summit with solar telescopes and eclipse viewers.
Royal BC Museum area – RASC members will be near the museum with solar telescopes and eclipse viewers.
University of Victoria Observatory – UVic is hosting a special public open house at the UVic Observatory (Bob Wright Building – 5th floor) on Monday, August 21, 2017 from 9 to 11:30 a.m. to view the solar eclipse. The eclipse will be visible at 90% coverage from Victoria. The eclipse begins at 9:08 a.m., reaches maximum coverage at 10:20 a.m., and will end at 11:38 a.m.. We will have eclipse glasses for the public to use and share, as well as special solar telescopes which will project an image of the Sun on a small white screen (attached to the telescope) to clearly show the eclipse. Looking at the Sun directly, even during maximum coverage, is damaging to your eyes. We request the public to leave the eclipse glasses behind after use. The event is free and no preregistration is necessary. The observatory will be open for the duration, and you are welcome to come and go as you wish. Please contact the Physics & Astronomy main office (250-721-7700) if you need any further information. Please note, pay parking is in effect on the University campus. The Bob Wright Building is easily accessible by bus.

Mr Eclipse – a lot of good information from eclipse viewing experts
On July 12th Victoria Centre’s Council approved a plan to replace the telescopes currently in our observatory with new and improved optics. The Technical Committee’s plan includes replacing our existing Meade 14” SCT and Tele Vue NP 127is apochromatic refractor with a 16” F/8 Ritchey Chretien (RC) optical system. The new gear will be mounted on our existing Paramount ME mount, giving us a simpler setup that is actually a bit lighter than the old configuration.
The cost of the new RC telescope and accessories will be about $14,000, depending on the US$ exchange rate. Most of the gear will be purchased from OPT Oceanside Photo & Telescope in California, since they sell their brand TPO Ritchey Chretien telescopes at very attractive prices, and we took advantage of a recent sale price. We expect to eventually sell our surplus instruments and accessories, but will keep the current setup in place until the new gear arrives and is installed, in order to maximize the availability of the VCO to members.
We will fundraise from our members to directly offset the upgrade costs, since Victoria Centre Council originally budgeted $7,000 for the upgrade some months ago.
Improved cool down time
new RC is a truss design open tube giving good airflow around the primary optics,
old SCT is a closed tube design with a corrector plate restricting air flow
Improved guiding accuracy
new RC system will use an in-line off-axis guider,
old SCT system uses a piggyback-mounted telescope for guiding
Improved pointing accuracy
new RC system has a fixed primary mirror,
old SCT system suffers from primary mirror flop
Improved light gathering and resolution
new RC system has a 16″ primary mirror
old SCT system has a 14″ primary mirror and a corrector plate
new RC system is a single optical tube that will be used for guiding, imaging and observing
old system included an SCT, a Hyperstar f/2 attachment, a 127mm apo-chromaic refractor, and a guide scope, all mounted piggyback and in a custom cradle
We wish to enter RASC’s 150th year in 2018 with a first-rate observatory!
Our target is to raise $5,000 from members over the next few months. Tax receipts will be issued for all donations.
Joe Carr is our fundraiser, so please contact him for questions about the new telescope or to donate – email or telephone 250-294-1992.
Bruce Lane is our Treasurer, who will issue tax receipts and account for all donations to Council and members – email.
The first fundraising event was held at the RASCals Star Party on Saturday, July 29th at 2PM in Metchosin House. Thanks to everyone who donated so generously – we are already over half way to our target!
Please note that proceeds of the sale of used astronomical equipment is highly variable and can take many months. RASC Victoria Centre and then all RASC members will be given first chance to purchase our surplus equipment. Please contact Joe by email or telephone 250-294-1992 if you are interested.
9:30 pm – Public viewing of the night sky with RASC telescopes
10:00 pm until dawn: observing! No white lights during this time, please
Cleanup – everyone please pitch-in & help
12:00 pm – early departures please!
PRIZE – Explore the Universe Guide; stainless steel coffee mug
PRIZE – Celstron Inspire 100AZ telescope
PRIZE – Skywatcher Heritage telescope
PRIZE – Eclipse Viewer kit; rechargable hand warmer
Please feel free to camp on the field with your tent, trailer or motorhome and setup your telescope and other astronomy gear. There is some power on the field for astronomy equipment, but no RV plug-ins please! Also, 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 on the access road beside the municipal hall with your headlights facing away from the field (towards the firehall). The same parking request applies to visitors for the evening – park beside the municipal hall and walk into the field.
Another year of Astro Café has concluded. I would like to thank Barb, Reg, and John for the great series of topics, photos, videos, and of course, snacks we shared. With the installation of the larger television screen earlier this year, it is much improved for the sharing of astrophotography, videos, and the like. Astro Café continues to be a well-attended centre event and we look forward to another year starting in September. If you have not been to Astro Café recently, or ever, I encourage you to come by one Monday evening. I don’t think you will be disappointed!
The 2017 Summer Star Parties at the DAO are in full swing and we have had some good observing weather. As we enter summer, the emphasis will be on solar astronomy and targets that can be seen while the sky remains light. If you are not already on the volunteer’s list, and want to help out, please send me an email at firstname.lastname@example.org. There are many more Saturdays on the calendar and new volunteers are most welcome.
As space exploration is in the news frequently, we have some great conversations at the star parties. I really enjoy sharing that time at the telescope that is often someone’s first time seeing a solar prominence or looking at the moon through a telescope. We’ve even had astronomical events that centre members have not seen before. For example, on 3 June, we saw the double shadow transit of Jupiter’s moons Ganymede and Io during the evening. That was a first for me and something I will look out for in the future. The shadow transit coincided with the Great Red Spot being visible so that was great all around!
With general interest in astronomy, I have long thought it is under represented in the school curriculum. Considering the major contributions of Canadian astronomers, it is surprising that our students do not have more exposure to space science and, in particular, the opportunity to take a senior level course in astronomy. I was very happy to learn that teachers at Victoria High School are working to correct that with the introduction of an Astronomy 11 course. The course launches in the 2017 – 18 school year and the initial impressions are that quite a few students are interested in taking this new course. That is a great step forward and I hope it proves to be a great success. As part of the launch of this new course, Victoria High School is hosting a Star Party on Saturday 17 June starting at 8:30 p.m. If you are in the area why not attend? Please see cuyeda.weebly.com/star-party.html for more information.
Finally, as a reminder, our RASCals Star Party will be held on weekend of 28 – 30 July on the District of Metchosin municipal grounds. Information will be posted on our website once we have more details about the events that day. Saturday 29 July has been identified as the National Star Party day with events taking place across Canada as part of the sesquicentennial. I hope many members will come to the party again this year.
Radio and Microwave Astronomy – History, Canadian Involvement, and Interesting Tidbits – Dr. Lisa Locke, NRC Herzberg
Radio astronomy started in the early 1930s as an electrical engineering project and it took many years for the optical astronomy community to include it under the gilded Astronomy umbrella. Early experimentalists had a field day with surplus World War II equipment and the increased world-wide collaboration between researchers. I will explain and guide through this history up to the present, contrasting the new radio astronomy with the classic well-understood optical ideas, highlighting Canada’s significant role in the growing field. Details on current instrumentation projects and observatories will also be presented.
Dr. Lisa Shannon Locke was born north of the 60th parallel in Hay River, Northwest Territories, Canada and received the B.Sc (Alberta, 1997), M.Sc. (Cape Town, 2001) and PhD (Victoria, 2014) degrees all in electrical engineering specializing in low-noise microwave astronomy instrumentation.
As a student, she worked at the Canadian Space Agency, CalTech’s Owens Valley Observatory and at the National Radio Astronomy Observatory in Green Bank, WV. After graduating, she spent five years as a receiver engineer at the Arecibo Observatory in Puerto Rico. Then in 2005 she joined the National Radio Astronomy Observatory, Socorro, NM building cryogenic receivers for the expanded very large array (EVLA).
Her PhD degree was advised by Prof. Dr. Jens Bornemann and the late Dr. Stéphane Claude of NRC Herzberg Institute of Astrophysics, Victoria, BC. Her thesis investigated the design and construction of a K-band (18 – 26 GHz) coherent 5×5 phased array feed for use on large radio astronomy reflectors. She is currently employed with NRC Herzberg and leads a multi-disciplinary project to build a S/C-band (2.8 – 5.18 GHz) cryogenic phased array feed receiver system.
I will start with a riddle this month. Question: What do you call the rainy day between 2 sunny days? Answer: Astronomy day.
Although the weather did not cooperate, this year’s Astronomy Day was a fantastic event. Thank you to everyone who contributed and especially Ken Mallory for getting all of us organized. I was pleased to see that there are a more organizations participating with us making it an even better. For example, Knowledge Network of BC approached us this year about showing Space Suite I and Space Suite II. If you have not seen these short videos they are very enjoyable; both are available on the Knowledge Network website. The Royal BC Museum is an excellent host so I would like to acknowledge their outstanding support.
Despite the rainy weather, we did have quite a good turnout on the hill for our first Summer Star Party so it can only get better with clear weather. As we have such a great facility on our doorstep it is wonderful that we can share it with the public. One of the goals with having more evenings this year is to have more visitors so I do hope we can achieve that goal.
At a recent Astro Café we were talking about apps and websites that we enjoy. One iOS app I shared, that is also available as a website, is called The Scale of the Universe 2. Based on a continuing progression of sizes centred on 1 metre, the user scrolls in either direction to see examples of things that are that microscopic and beyond all the way to some of the largest known objects. There are a number of named astronomical objects included so this is a tool that can be used to show comparative sizes. Did you know that Jupiter would fill more than a third of the distance from the Earth to the Moon? If you look around the 108.5 m zone you will see this comparison. The Sun appears around 109 m but you don’t see Antares until 1012 m. It is quite fascinating. If you are interested in the miniature world, great examples of the very small are there as well. Check it out; it is very well done.
A reminder that we are back in our normal room, Bob Wright Centre A104, for our monthly meeting on 10 May.
Wednesday, May 10th 2017 at 7:30PM, University of Victoria, Bob Wright Centre Room A104 – RASC Victoria Centre’s Monthly Meeting
The past 20 years has seen the dawn of a new field in astronomy: extrasolar planets, or exoplanets for short—planets orbiting around stars in other solar systems. We now know that the Universe is teeming with exoplanets, thanks largely to the help of the Kepler space telescope, which finds exoplanets by seeing their shadow on its much brighter host star. Although there are a number of different methods of finding exoplanets, my research focuses on an exoplanet detection technique called direct imaging, which as the name suggests is designed to directly image these other worlds. But this is not as simple as it sounds, and it ultimately requires the use of our most powerful telescopes and specially designed optical systems in order to distinguish an exoplanet from the overwhelming glare of its host star. In light of the upcoming total Solar eclipse in August 2017, I’ll describe one of these instruments, called a coronagraph, which was first used to observe the Solar Corona without the help of the Moon! After outlining these challenges, both in engineering and in physics, and how they can be overcome, I will highlight the main instruments and detections in this field of direct imaging, and also compare the advantages direct imaging has over other techniques. Come prepared to see real pictures of other worlds!
Benjamin Gerard is a 1st year PhD student in Physics and Astronomy at UVic. He did his Bachelors in Physics and Astronomy at University of Colorado at Boulder and is originally from San Francisco, CA. His research, supervised by Dr. Christian Marois, focuses on optical design and image processing algorithms for instruments made to directly image exoplanets.
The Friends of the Dominion Astrophysical Observatory (FDAO) and RASC Victoria Centre will be hosting nineteen Saturday evenings at the DAO, featuring guest speakers, solar and nighttime observing with telescopes provided by RASC Victoria Centre volunteers, tours of the historic Plaskett telescope, and more! Rain or shine, we will have something for everyone to experience.
Dates begin with International Astronomy Day on April 29th. Here are all the dates:
May 6th, 13th, 20th, and 27th
June 3rd, 10th, 17th, and 24th
July 8th, 15th, 22nd, and 29th
August 5th, 12th, 19th, and 26th
September 16th and 23rd
PLEASE NOTE: due to the extreme traffic congestion in previous years, admission is now by ticket ONLY. Tickets are FREE and will be available during the week preceding each Saturday evening from our EventBrite site: http://daostarparties.eventbrite.ca
See you there!
Summer Star Parties at the DAO run every Saturday evening from April 29th to September 23rd with some exceptions as noted in the schedule above. To enhance your experience please note the following venues before you arrive. Activities are broken up in to seven main areas,
Lecture Hall – This summer we have a full slate of topical presentations from the astronomy community which includes researchers, authors and passionate amateurs. There are possibilities of surprise guest speakers. Come early most presentations start at 8 p.m. and some though not all repeat in the evening.
Plaskett Dome – The dome is a heritage site, and not to be missed. Tours are approximately 45 minutes long and start at 7:45 p.m. Two other tours start at 8:30 p.m. and 9:15 p.m.
Planetarium – Planetarium shows run 6 times during the evening and are approximately 30 minutes in length. Come inside and learn about the constellations, and even a little sky lore!
16” Telescope – This research-grade telescope was originally located on Mt Kobau near Osoyoos for site testing towards potentially building an observatory there. It was then moved here to the DAO, and then from another area on the DAO property to this site when the Centre of the Universe building was constructed in the early 1990s. It is now available for viewing “live” through an eyepiece. The telescope is open subject to weather conditions most of the evening.
RASC Member Telescopes – Royal Astronomical Society of Canada members have been long standing participants at Saturdays nights at the DAO for nearly 100 years. Weather permitting, members will take you on a telescopic tour of the evening sky.
Information Area – There are volunteers available to help you with your evening visit and if you’re interested they can let you know how you can get involved in astronomy activities in Victoria. Look for kid friendly displays from Science Ventures in this same area.
Interpretive Centre Displays – The displays from the former interpretive centre show Canada’s role in astronomy and contain a number of historical artifacts of interest.
