September 17 2018: 21P Comet Giacobini-Zinner

Posted by as Observing Highlights

From an email post to RASC Victoria on September 17 2018: 21P Comet Giacobini-Zinner

It was clear enough last night to get a quick snapshot of the comet from the driveway. I had to get the light stand out with a large sheet of black foamcore to block the streetlight nearby. Light pollution was a challenge but I was able to collect 16 one minute images and do a simple stack in Maxim DL. It’s nicely framed by the open cluster M35 just underneath Auriga, IC443 a supernova remnant in Gemini and NGC2174 a HII emission nebula in Orion. Hopefully I’ll be able to get a better shot from darker skies this week :-)

David Lee

A response from Bill Weir:

That’s really nice David. In the early morning when the comet was within M35 I took the chance and drove to the cricket pitch in Metchosin even though 90% of the sky was cloud. This is my write up of the event.

Well that was fun and reconfirmed to me the value of being prepared. Around 0030hrs PDT I was putting the dogs out and looked up and saw a clear patch of sky heading to the east. I grabbed my eyepiece case, jumped in the car and headed to the cricket pitch as the 6 inch dob had already been in the car for days. It took over an hour for the clearish patches to make their way across the sky but that was OK as it gave me a chance to collimate the scope and check out various deep sky objects along the way. Eventually the left toe of Gemini (their toe) peaked through the clouds and I was able to pick out M35 with the 15X70 binos. No comet was visible so I panned about but couldn’t make out anything. Through the scope at 38X with a 31N it was a beautiful view of M35 and NGC 2158 but no comet was visible in the area. I upped the power to 60X and focused on M35 still nothing until I began to notice a fuzziness within the eastern side of the cluster to the SE(?) of a beautiful curving chain of stars. As I advanced though 120x and then finally to 200X it became apparent this was the comet fully within this beautiful cluster! It was similar to this image except move the comet a bit down and to the left.

In the end it reminded me in a way of the planetary nebula NGC 2438.

Shortly after drinking in the view clouds moved in and the show was over. It wasn’t my best comet observation by far due to low altitude in the sky and being over Victoria to the south east. That was OK though because my feet were freezing as good footwear was the one thing I neglected as I raced out the door. Drove off the field at 0215 PDT and was soon tucked in bed. Many like the phrase “make hay when you can” but I prefer,”you can’t dance at the party if you don’t show up”. This means go out even if the weather doesn’t seem optimal or you won’t see things at all.

Rain or shine, we will have something for everyone to experience.

Time: 7:15 pm to 10:45 pm

Dates begin with International Astronomy Day on April 21st . Here are all the dates:

  • April 21st and 28th 
  • May 5th, 12th, 19th and 26th 
  • June 2nd, 9th, 16th, 23rd and 30th 
  • July 7th, 14th and 21st  *note* the DAO site has scheduled maintenance that does not allow us to open July 28th
  • August 4th, 11th, 18th and 25th
  • September 1st 

Site Line Work Only

Saturday Star Parties at the DAO run every Saturday evening from April 21st to September 1st. To enhance your experience please note the following venues before you arrive. Activities are broken up into seven main areas,

  1. Lecture Hall – This season 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 8:30 p.m. and some though not all repeat in the evening.
  2. Plaskett Dome – The dome is a heritage site, and not to be missed. Tours are approximately 30-45 minutes long and start at 7:45 p.m. (30 min) Two other tours start at 8:45 p.m. (45 min) and 9:30 p.m. (45 min). Special Kids Tour 8:15 p.m. (30 min)
  3. 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!
  4. 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 on many of the Saturday nights.
  5. 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.
  6. 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. Kid friendly programming is available in this same area. FIRST Robotics BC will be in attendance several times during the summer.
  7. 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.

On the Origin of Life – Organic Molecules in Space; the Crucible; Evolvability- Dr. Dorothy Paul

Abstract:

Earth is the only place in the Universe that we know harbours life. We understand roughly how the Solar System formed, some 4.7 billion years ago, and how once established on the 3rd planet from the Sun, life acted in concert with geological/chemical processes to transform it into the planet we now live on. What we don’t know is where or how life got started in the first place. However, by integrating results from recent geological, paleontological, and biological research, increasingly plausible hypotheses are being constructed. Improved understanding of the evolutionary history of our life-infested planet enriches our lives and informs future studies on earth and in space.

Bio:

Dorothy Paul is a biologist and amateur astronomer. Prior to retirement from the University of Victoria, her research was in neuroscience and evolutionary neurobiology.

Deep (Machine) Learning with Neural Networks – the Second Industrial Revolution – Karun Thanjavur

Abstract:

Artificial intelligence (AI), specially Deep (Machine) Learning are already ubiquitous in everyday use, and have been called the second industrial revolution. Deep Learning algorithms, called Neural Networks, thrive on Big Data, the happy ‘problem’ we now face of the enormous amounts of data available in this digital era. In astronomy too, telescopes will soon routinely produce terabytes of data every night. Piggybacked on the impressive recent advances in high performance computing, neural networks are trained on these available large datasets to then perform a variety of human-like tasks, such as identifying subtle patterns, realtime decision making, forecasting based on experience, and so on. In this presentation I aim to provide an overview of this rapidly burgeoning field, explain in simple terms the working of a neural net, and illustrate the principles with a working model.

Bio:

As a research astronomer, I am excited by the availability of huge public datasets, which I may harness for my own research questions using the proper data analysis tools. Given the enormous data volume, I have recently begun harnessing the powerful techniques of deep learning to tease out complex correlations and thus illustrate the underlying physical principles. These science explorations of the Universe, coupled with the equally fascinating world of Artificial Intelligence and Big Data, come after a full career as a mechanical engineer, specializing in control systems and robotics. Born and raised in a small town in South India, I completed my education up to a bachelor’s degree in engineering there, before moving to Canada to pursue graduate studies first in Robotics, and later in Astrophysics. Even though undergraduate teaching is the principal focus of my current position as a senior astronomy lab instructor at UVic, I work hard to keep my research interests alive. I also enjoy sharing the excitement of science and my research efforts with the public through many outreach initiatives.​

How Things Might End -Thoughts on the various ways the Universe will unfold with time – Dr. Doug Johnstone

Abstract:

In this talk I will consider possible ways in which things might end, from the destruction of the Earth, the evolution of the Sun, rare but dangerous events within the Galaxy, and finally the evolution of the Universe itself. Beware!

Bio:

Dr. Doug Johnstone is a Principal Research Astronomer at NRC’s Herzberg Astronomy and Astrophysics. For two years he was the Associate Director of the James Cleark Maxwell Telescope, a 15-m telescope on Maunakea devoted to observations of the sky at sub-millimeter wavelengths. Doug’s main research interests follow the formation of stars and planetary systems. He began his professional life as a theorist at the University of California, Berkeley, working on the evolution of circumstellar disks around young stars, back before extra-solar planet detections were common. Today, Dr. Johnstone’s research focuses on the formation and evolution of structure in molecular clouds, attempting to disentangle the physical processes through which a molecular cloud sheds into individual stars and planets.

Kitt Peak and the Sonoran Desert – David Lee

Abstract:

In May 2018 I travelled to Tucson Arizona to visit Kitt Peak, an epic collection of 24 telescopes in the Sonoran Desert. Twelve miles up a mountain road at an elevation of almost 7,000 feet it was built in the ’60s. It was and still is the site of many astronomical discoveries and research. The beautifully dark skies were also my opportunity to photograph the Milky Way away from Victoria’s light polluted skies. Come and see the day and night time images from the peak.

Planets Under Construction: How to Study a Million-Year Process – Dr. Nienke van der Marel

Abstract:

Exoplanets are everywhere! In the last 25 years, thousands of exoplanets have been found throughout the Milky Way. But if they are so common, why is it that we still don’t know how they are formed? With the ALMA telescope we can now finally zoom into the birth cradles of planets: dusty disks around young stars. The spectacular images have given us new insights, but also raised many more questions regarding the process of planet formation.
