President’s Message – October 2018

Posted by as President's Message

Thank you to everyone who was involved in the RASCals Star Party this year. We tried out a new venue in Central Saanich and it looks to have a lot of potential. If only the weather had cooperated! A number of centre members have observed from the site in the past with success. Despite the rainy weather, we did have some great talks and our first attempt at a star party barbecue went well.

I am pleased to report that our application for special project funding was approved. Jim Hesser, John McDonald, and David Lee will be putting together a visual display for the second concert of William Herschel’s music. The application sought funding from the RASC special project fund to cover the costs of some of the equipment needed for the concert. This concert will be part of the fourth season of the explorations in 18th century music. This year’s offering is called On the Construction of the Heav’ns and will feature a Baroque chamber orchestra. The venue is Christ Church Cathedral again this year and the concert will take place on Friday, November 16. There will be a pre-concert talk at 6:45 p.m. followed by the concert at 7:30 p.m. More information is available on the Christ Church Cathedral website and tickets are $30 each available from Ticket Rocket.

Save the date for our Annual General Meeting on the evening of Saturday, November 17. Evening festivities include a dinner, speaker, annual awards, and election of council. Please let me know if you by email at president@victoria.rasc.ca if wish to attend the dinner. The cost is $40.

We are now accepting nominations for the annual awards. In particular, we are seeking nominations for the Newton-Ball Award. Please see the website for details of the award and how to nominate a member to receive the award.

We will be looking for members to join the council this year. It has been a great experience for me to become part of the council and I encourage everyone, even if you’ve just joined, to consider putting your name forward. Sherry, our past president, will be coordinating the nomination process so please contact her at pastpres@victoria.rasc.ca if you would like more information and to put your name forward.

October Speaker: Coronal mass ejection evolution and their effects on galactic cosmic rays and planetary magnetospheres.

Coronal mass ejections (CMEs) are large eruptions of plasma and magnetic field into interplanetary space originating in the Sun’s atmosphere. CMEs interact with the environment that they propagate through; for example, they are the most common cause of planetary space weather, and they also modulate the flux of galactic cosmic rays. Because CMEs can be associated with strong southward magnetic fields of long duration, high velocities, enhanced dynamic pressures, and solar energetic particles, they are strong drivers of geomagnetic storm activity at Earth. The effects of CMEs on Earth’s magnetosphere have been studied for many decades; on the other hand, studies of CME effects on other planets are only now becoming possible with a number of spacecraft in orbit around inner solar system planets. This new data enables us, for the first time, to directly observe how CMEs cause space weather on other planets, and also how CMEs change during propagation from the Sun to Earth. In this talk, I will present efforts to investigate how CMEs evolve as they propagate outward from the Sun, in order to better predict their effects on planetary magnetospheres. I will also showcase how CMEs affect Mercury’s magnetosphere as well as the flux of galactic cosmic rays in the inner solar system.

Dr. Reka Winslow is a research scientist in the Space Science Center at University of New Hampshire, where she also conducted her postdoctoral work. She holds a Ph.D. in geophysics, having specialized in space physics and planetary science at UBC. She has over 10 years of experience conducting research in space physics. Her work bridges the fields of heliophysics and planetary science, by focusing on observational studies of coronal mass ejections, interplanetary shocks, galactic cosmic rays, and solar energetic particle events to better understand their evolution in the inner heliosphere and their interaction with different planetary magnetospheres in the solar system. She is a member of the science team for the CRaTER instrument onboard the Lunar Reconnaissance Orbiter, and was a member of the MESSENGER science team while the spacecraft was orbiting Mercury.

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.

President’s Message – September 2018

Posted by as President's Message

I hope everyone had an enjoyable summer and had many opportunities to enjoy the night sky.

I am pleased to announce that our very own Dr. Chris Gainor was elected president of the Royal Astronomical Society of Canada at the General Assembly in Calgary. It has been 40 years since another Victoria Centre member, Dr. Alan Batten, was the national president. Please join me in congratulating Chris on his election.

The Victoria Centre had a great summer of outreach events in 2018. Thank you to all everyone who organized and participated. We had another successful season of summer star parties at the Dominion Astrophysical Observatory; there were a total of 19 well-attended Saturday evenings offered. A group of RASCals were at the Saanich Strawberry Festival with solar viewing in July. For the second year, members had their telescopes at the Fort Rodd Hill Star Gaze in August. There was an event on Pender Island on the same evening. And, there was the annual participation at the Saanich Fair over the Labour Day weekend. Some members also participated in a number of special events such as instruction and observing offered to guides and cadets. It was a busy and rewarding summer!

It was unfortunate that the Fort Rodd and Pender Island events coincided with the worst viewing conditions that I have experienced. In looking at Saturn, it was a fuzzy football-shaped object instead of its normally stunning planet with a fabulous ring. As I recall, that was one of the first evenings when forest fire smoke was in the skies above us. That really had a major impact and I am concerned that an increase in the severity of our forest fire seasons will make smoke a regular part of our summer.

With the arrival of September, we return to our normal schedule of weekly Astro Cafés starting on Monday, September 10 and monthly meetings resuming on Wednesday, September 12. As a reminder, we will be voting on our revised bylaws at the September 12 meeting.

We have another major event in September this year and that is our annual star party. It is taking place at our new venue on the grounds of St. Stephen’s Church in Central Saanich. That takes place September 7 to 9 and I hope many members are able to attend. Please see the website for the schedule.

Save the date for our Annual General Meeting on the evening of Saturday, November 17. Evening festivities include a dinner, speaker, annual awards, and election of council. We will be posting information about the meal options and cost once that is finalized.

We are now accepting nominations for the annual awards. In particular, we are seeking nominations for the Newton-Ball Award. Please see the website for details of the award and how to nominate a member to receive the award.

We will be looking for members to join the council this year. It has been a great experience for me to become part of the council and I encourage everyone, even if you’ve just joined, to consider putting your name forward. Sherry, our past president, will be coordinating the nomination process so please contact her at pastpres@victoria.rasc.ca if you would like more information and to put your name forward.

September Speaker – Planets Under Construction: How to Study a Million-Year Process

Posted by as Meetings

By Dr. Nienke van der Marel

Wednesday September 12th, 2018 at 7:30 PM

Room A104 Bob Wright Centre UVic

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.

Dr. Nienke van der Marel is an NRC postdoctoral research fellow at the Herzberg institute. She received her PhD in 2015 at Leiden University in the Netherlands, her country of birth. After that, she spent two years at the University of Hawaii as Parrent research fellow, before joining the Herzberg institute in November last year.

Mars Opposition 2018

Posted by as Observing Highlights

On Friday July 27th 2018 Mars will make it’s closet approach to Earth in 15 years.

RASC Victoria Centre: David Lee &emdash; The Planets at Cattle Point
Planets visible from Cattle Point – by David Lee

This occurs when Mars, Earth and the Sun are aligned with Mars located on the opposite side of Earth from the Sun. Mars will slowly rise on the eastern horizon late that evening … not the best viewing situation. A major dust storm developed on May 31st and has obscured details of the Martian surface. (see image below) Surface details will gradually re-emerge later this Summer as the dust storm subsides.

The viewing characteristics of Mars as seen from the Victoria area are tabulated below for the remaining DAO Saturday Night Summer Star Parties of the season.

Notice that the appearance of Mars (angular diameter) will decrease very slowly after the opposition. One week following opposition the angular diameter will only be 0.5% smaller but Mars will rise earlier and surface features may start to re-emerge.

Evening viewing conditions of Mars therefore will be more favourable and convenient in August.
Consider attending a DAO Saturday Night Star Party this August.
Volunteers of RASC will be there to share the night sky with their telescopes.
Click here to obtain free Star Party tickets. Note: No Star Party on July 28th.

In the Victoria area the best evening views of Mars are obtained with an unobstructed view of the southeast such as: Cattle Point Urban Dark Sky Park, Clover Point, Island View Beach, and Mount Tolmie. In the late evening Mars will appear fairly low in the southeast as an exceptionally bright red dot. It is hard to miss. Check it out.

Inaugural Transboundary Fireworks Festival

Posted by as Observing Highlights

By Reg Dunkley

On a mild July 4th evening about 10 RASCals assembled at Cattle Point Urban Dark Sky Park for the Inaugural Transboundary Fireworks Festival. Attendees were rewarded with spectacular views of two July Forth Fireworks shows. Between 10 PM and 10:15 PM Friday Harbour on San Juan Island took the stage. Terrain blocked some of the low level displays but the airborne clusters filled the field of view of most scopes. The main event occurred between 10:30 PM and 10:50 PM when Fisherman Bay on Lopez Island launched their salvo. Although slightly farther away we enjoyed an unobstructed view of the Lopez conflagration.

A variety of scopes were deployed including refractors, newtonian reflectors, spotting scopes, binoculars as well as an 8 inch Schmidt Cassegrain. In order to squeeze in the view RASCals resorted to lower magnifications. This confirmed that you do not need a big scope to enjoy the show.

It took about one minute 20 seconds for the muffled booms to arrive on the scene. This soundscape combined by the spontaneous whoops and ah’s from the RASCals added to the party atmosphere. It would have been nice if we were able to transition from the fireworks to star gazing … but clouds intervened.

Should we try again next year? Randy Atwood’s attached photo captured Chris Aesoph giving it two thumbs up! So I reckon that is a yes. It was a RASCal Worthy event.

The attention the photons received was well deserved.

Thanks to all the attendees.
