President’s Message April 2020

Posted by as News, President's Message

The tipping point occurred near the 15th, the Ides of March. Just a few days earlier at the Victoria Centre Monthly Meeting 50 RASCals enjoyed the entertaining talk by Dr. Tyrone Woods which involved both supernovae and sword fights. While details of the approaching Astronomy Day were presented there was tension in the air and it was recommended that members monitor HealthLinkBC.ca. By the 17th, Saint Patricks Day, schools were cancelled, the gates to the DAO were locked and even the Pubs were closed! In almost an instant, astronomy “outreach” events Astronomy Day and Saturday Star Parties together with “in-reach” events such as, Astro Cafe, Monthly Meetings, VCO sessions and the 2020 Vancouver General Assembly were cancelled. What lead to this astonishing turnaround? Perhaps it was the eerie images of Italian landmarks, totally devoid of people. Maybe it was the grime graphs of soaring death totals. Or could it be the announcement that even Tom Hanks was not immune to CoVid-19?

Sporting activities involving crowds like hockey and basketball were among the first casualties. In contrast, the stillness, peace and wonderment of observing the night sky can be safely experienced in isolation. One of the joys of the astronomical community, however, is sharing these experiences with others. A “Virtual Astro Cafe” has been set up on https://victoria.rasc.ca and it allows you to share your stories, images and links. We have already enjoyed a strong response and we encourage you to forward your contributions to president@victoria.rasc.ca. One of the things missing from this Virtual Astro Cafe, however, are the comments, questions and banter that add a special touch to the authentic Astro Cafe. The hosts of Astro Cafe are addressing this shortcoming by holding Astro Cafe Webinars using software called Zoom. It is scheduled for Mondays at 7:30PM and all you have to do is click on the link provided by the email from the Astro Cafe host and respond to one or two prompts. It is a surprisingly effective way to achieve a sociable connection at a safe distance. Give it a try!

The mention of Tom Hanks recalls his portrayal of Astronaut Jim Lovell in the epic movie Apollo 13. The 50th anniversary of the explosion aboard Apollo 13 takes place on April 13th. This is a validation of bad luck for the superstitious! The remarkable success of the earlier Apollo missions fostered a sense of complacency among much of the population. This episode, however, dramatically illustrated the dangers and complexity of these space missions and riveted the attention of the world until the capsule safely returned. You may not be aware of the Victoria connection of this adventure. Ernie Pfanneschmidt and Frank Younger of the DAO were atop Mount Kobau during this mission and successfully photographed the oxygen cloud that formed in the wake of the explosion. The 16 inch telescope that they used is now residing in the dome connected to the Centre of the Universe. To learn more see pp 6-7 Sep 2018 SkyNews. Pause and reflect on this historical role when you next peer through the eyepiece of this scope.

Although most Victoria Centre events have been cancelled until further notice, there may be an interesting spectacle to anticipate. Victoria RASCal Martin Gisborne recently imaged comet C/2019 Y4 (ATLAS) discovered by the ATLAS (Asteroid Terrestrial-impact Last Alert System) survey on December 28, 2019. Visit Virtual Astro Cafe to view this image It is currently situated above the plane of the Solar System moving from Ursa Major to Camelopardalis. It will swoop southward and make its closest approach to Earth on May 23rd. Some have speculated that it will brighten significantly on approach. Prediction of any sort is a reckless business but it might provide a welcome distraction from the global pandemic.

As we work our way through this challenging time remember that we are all in this together. So keep at a safe distance, be kind and when skies are useable … look up.

March 2020 Speaker: When Stars Explode: Understanding Supernovae from Tycho to Today

Posted by as Meetings

Dr. Tyrone Woods

7:30PM Wednesday March 11th 2020, Room A104 Bob Wright Centre, UVic

In 1572, a new “star” appeared in the sky that forever changed the way we think about the Universe. Identified by famed Danish astronomer Tycho Brahe, this incredible event is now understood to have been the explosion of a dead star — a supernova. Since then, supernova observations have illuminated the Cosmos, revealing everything from the origin of the iron in our blood to the final fate of the Universe. In this talk, I’ll outline a brief history of supernova astronomy, culminating in the cutting-edge work being carried out in Victoria and across Canada today to understand why and how some stars explode, and the lasting impact of their explosions and remnants in our Galaxy and beyond.

Dr. Tyrone E. Woods is a research associate and Plaskett Fellow at NRC-Herzberg in Victoria. There, he studies the physics of some of the most energetic events in the Universe, by combining theoretical models with observations across the electromagnetic spectrum. Before returning to Canada, he completed his PhD at the Max Planck Institute for Astrophysics in Munich, Germany, and held research positions in Australia and the UK.

President’s Message March 2020

Posted by as News, President's Message

This is the inaugural Presidents message for my second and final term as President of the Victoria Centre of RASC. I would like to thank members of the Council and other active members for their support in the past year. A special salute to our Treasurer Deb Crawford who was busy sorting out our year end finances when we learned that our AGM planned location, the Cedar Hill Golf Course, was no longer available. She rallied to the cause and soon found an alternate venue that ticked all the boxes. Her initiative was key to the success of the AGM and I am very grateful for her contribution. I would also like to thank our Secretary Barbara Lane for presenting our Annual Report in an entertaining manner and Bruno Quenneville for organizing the awards. Our speaker, Mary Beth Laychak, delivered a most interesting and entertaining presentation on the history of the CFHT and we are fortunate that NRC Herzberg helped make that happen.

Thanks must also go to Marjie Welchframe, Mandy Lee and Bill Weir for stepping up and joining the Victoria Centre Council. Their added support and David Lee’s generous offer to organize Astronomy Day convinced me to stay on for a second term. I was, however, a little disappointed that there were no takers for the position of first Vice President. This places our organization in an awkward position. Our constitution prohibits the President from serving more than two consecutive terms. As a consequence if the current situation stands by next February the President’s position will be vacated with no groomed successor to assume the mantle.

The Victoria Centre is a vibrant and active organization and a leadership role may seem intimidating to some. A number of measures are being taken to make this position less daunting. An operators manual is in the works that will provide step by step instructions for major events such as Astronomy Day, the Victoria Centre Star Party, The Saanich Fair Outreach event and the AGM. Saturday Night Star Parties at the DAO offer an incredibly rich and focused opportunity for Astronomical Outreach. The number of these events have nearly tripled since 2015. In order to accommodate this increase we have attempted to trim our sails and have withdrawn from some of the less focused outreach opportunities. Meanwhile “In-reach” activities like Astro Cafe have grown in popularity and help to engage new members and recharge veteran RASCals with more knowledge, energy and enthusiasm.

The primary duty of the first Vice President is to schedule and introduce speakers for the monthly meetings. NRC Herzberg has been very supportive in this regard and the following speakers are already scheduled for the remainder of the season:
Wednesday March 11th Dr. Tyrone Woods – Understanding Supernovae from Tycho to Today
Wednesday April 8th: Dr. Matt Taylor – Role of Dwarf Galaxies & Globulars in Galaxy formation.
Wednesday May 13th: Dr. JJ Kavalaars – An Update on Arrokoth (aka Ultimae Thule)
Wednesday June 10th: Dr. Abedin Abedin – Modelling Meteoroid Swarms

That only leaves 6 more talks to schedule until the next AGM! So please give the First Vice President role serious consideration. It is a great opportunity to deepen your involvement in this remarkable organization. For 106 years the Victoria Centre has been dedicated to its primary mandate: to stimulate interest and to promote and increase knowledge in astronomy and related sciences. By stepping up you would help keep this wheel turning and make an important and satisfying contribution.
Usable Skies
