Vancouver weather: Vibrant northern lights display possible



Metro Vancouverites might have to pick their jaws up off the floor as stormy solar activity sets the ideal conditions for a vibrant northern lights display in the region over the weekend.

Weather dependent, a geomagnetic storm has mixed up the ideal solar cocktail for the haunting green glow to reach Canadian cities as far south and wide as Vancouver, Toronto, and Charlottetown, P.E.I.

The National Oceanic and Atmospheric Administration (NOAA)’s Space Weather Prediction Center has issued a G-1 minor geomagnetic storm warning for Friday, Feb. 17, and a G-2 moderate geomagnetic storm warning for Saturday.

According to the University of Alaska Fairbanks (UAF), auroral activity will be “high” on Friday, with “highly active displays” possible from Yellowknife down to Edmonton and Winnipeg and as low as Seattle, Boston, and Halifax


The university’s online aurora monitor map shows what regions the aurora’s green glow will likely reach, as well as other areas where there is less of a possibility. Additionally, there is a brief description below the map of the aurora activity on that particular day. You can switch to other days to see the forecast, too.

Unfortunately, the Metro Vancouver weather forecast includes a 60 per cent chance of showers Friday night, which means that cloud coverage might prevent a viewing opportunity.

Metro Vancouver weather forecast and a possible potent northern lights viewing opportunity

While the forecast includes cloudy periods overnight Saturday, a possible break in the cloud coverage could allow for a spellbinding display of the dancing lights.

High highly-active auroral activity is expected and the map shows the potent green glow extending past Vancouver and Toronto. In fact, displays are even expected to be possible “visible low on the horizon from Salem, Boise, Cheyenne, Lincoln, Indianapolis, and Annapolis,” according to the UAF.

Another viewing opportunity is also possible Sunday, with active auroral displays possible overhead from “Inuvik, Yellowknife, Rankin, and Iqaluit to Juneau, Edmonton, Winnipeg, and Sept-Iles, and visible low on the horizon from Vancouver, Great Falls, Pierre, Madison, Lansing, Ottawa, Portland, and St. Johns.”

The Vancouver weather forecast currently includes rain on Sunday but precipitation is difficult to predict in advance. That said, the displays will be better on Saturday if viewing is possible.

Light pollution in large cities makes the aurora borealis difficult to observe, but not impossible, given the right circumstances. But your best bet for viewing that hypnotic green glow is up north or outside of the city.

Going back to the moon: 'This is Canada on the world stage, doing big things' –



WASHINGTON — Ask Marc Garneau if he’d go back to space and the first Canadian to ever make the trip doesn’t hesitate: “In a wink.”

It’s another matter entirely, of course, whether the now-retired former astronaut and Quebec MP —  at 74, he finally gave up his seat in the House of Commons just three weeks ago — still has the right stuff.

“You always wonder, when you reach a certain age, whether you would still have that capability that you had when you were younger,” said Garneau, who flew three Space Shuttle missions between 1984 and 2001.


“Having flown three times, I consider myself blessed beyond any reasonable expectation in life.” 

Now the country’s pre-eminent “elder statesman” of space, Garneau has long waited for the day when he’ll be joined in the pantheon of pioneering explorers by the next astronaut to earn the “first Canadian” honorific. 

Who will it be? The world finds out Monday. 

That’s when NASA and the Canadian Space Agency will introduce the four astronauts — three from the U.S., one from Canada — who will steer the next stage of an ambitious plan to establish a long-term presence on the moon. 

Scheduled to blast off as early as November 2024, Artemis II will be the first crewed mission to the moon since the final Apollo mission took flight in 1972. It will also be the first time a Canadian has ventured beyond Earth’s orbit. 

Canada’s astronaut corps currently comprises four people, including David Saint-Jacques, an astrophysicist and medical doctor from Montreal and the only member of the group who’s already been to space. 

Saint-Jacques, 53, flew to the International Space Station in 2018. He was selected for the corps in 2009 alongside Jeremy Hansen, 47, of London, Ont., a colonel and CF-18 pilot in the Royal Canadian Air Force. 

Joining them in 2017 were test pilot and Air Force Lt.-Col. Joshua Kutryk, 41, from Fort Saskatchewan, Alta., and Jennifer Sidey, 34, a mechanical engineer and Cambridge University lecturer from Calgary.  

“I’m not in any way jealous or envious,” Garneau said. “I’m just so excited that we are now taking Canada on what I would say is a major, major step forward.” 

It’s not quite the giant leap of 1969, but it’s close — about 7,400 kilometres away, to be precise. 

The four Artemis astronauts will encircle their home planet before sling-shotting into deep space for a figure-8 manoeuvre around the moon, making Canada and the U.S. the only two countries to ever pass over the dark side of the lunar surface.

“When I think back on 1984, when I first flew, we didn’t know what might happen after that,” Garneau said. 

“To now have the opportunity for Canada to be only the second country to have an astronaut go on a lunar mission — this is extraordinary.” 

It’s also the product of a tremendous amount of hard work and investment, said Western University professor Gordon Osinski, director of the school’s Institute for Earth and Space Exploration. 

Osinski spent the bulk of last week in Houston, taking part in simulated spacewalks to better learn and understand how best to conduct the geological work future astronauts will be required to do on the lunar surface.

While that research isn’t directly related to Artemis, it’s bound to be a key factor down the road as the ultimate mission continues to evolve into something that will bear little resemblance to its Apollo ancestors. 

“I can do field geology on Earth with a Star Trek-like instrument that tells me the chemistry of a rock. It wasn’t even imagined 50 years ago,” Osinski said. 

“So as we progress in the whole Artemis program, I think you’ll really see 21st-century space exploration like we might imagine from Star Trek and things.”

Even now, Osinski is still incredulous that Canada managed to secure a spot on Artemis II — and he credits everything from the country’s geographical and economic ties with the U.S. to the ongoing work of the Canadian astronaut corps. 

Then there’s the Canadarm, the articulated remote manipulators that became a fixture of Space Shuttle and International Space Station missions and a point of national pride for countless Canadians of a certain age.

“The U.S. has let go and said, ‘OK, Canada, we trust you enough that we’ll literally put the lives of our astronauts in your hand,'” Osinski said. 

“So that trust maybe goes a long way to explain how we did it.”

 The plan is to put a man and woman on the moon in 2025 in service of the ultimate goal: eventually dispatching astronauts to Mars. And Canada is expected to play a critical role going forward. 

“We’re going back to the moon. The moon, that’s a big thing,” Innovation Minister François-Philippe Champagne said last week. 

“This is Canada on the world stage, doing big things.”

That, ultimately, could be Artemis II’s biggest legacy for Canada: inspiring the next generation of astronauts in much the same way that Apollo did all those years ago. 

This time, though, the visuals will be spectacular.  

“As much as we get excited about robots and the Canadarm and things, having a personal experience in that could be a huge moment and a big milestone for the Canadian space program,” Osinski said. 

“There’s just something about having an astronaut do that.”

After sunset, see the 5 planets in the sky



This chart shows a westward view after sunset on March 30, 2023. Jupiter is getting harder to see, and the Sun is falling into the setting light. But Mercury will rise in the west — every evening — and rise throughout early April. Note that Uranus is close to Venus, but not shown. We show Uranus in the chart below. By way of illustration Used with permission.

How to see 5 planets

This week (late March 2023), you can see five planets lined up in our evening sky: Venus and Uranus, Jupiter and Mercury and Mars. Gianluca Massi of the Virtual Telescope Project in Rome, Italy, showed them through a telescope earlier today (March 29). To enjoy his presentation, watch the video below. In addition, you can see them in the sky, perhaps, if your sky conditions are very good, and you have a sharp eye.

As soon as the sun sets, the planets are positioned in a gentle arc across the evening sky, following the sun’s path across our sky. Likewise, the Moon and the planets also follow the eclipse.

How can we see the planets? Go out around sunset and look west. Among them you can easily spot the bright planet Venus.

Then use binoculars to scan the planet Uranus next to Venus.


Then aim your binoculars low in the sky, near the point where the sun is setting. That is where you will find Jupiter and Mercury.

Then look high in the sky — still see the eclipse or the path of the Sun — to Mars.


Guide to Planetary Viewing

Venus and Uranus. Of these five planets, Venus is the brightest and Uranus is the dim. These two are close together in the sky. Venus is easily visible to the eye. It is the first “star” (actually, planet) to come into view. Uranus shines at +5.8 magnitudes. This is theoretically obvious. But, in practice, you need a dark sky and a telescope to find it. It was roughly 1.5 degrees or three moon widths from Venus earlier this week. Uranus will be closest to Venus on Thursday, March 30.

Thursday and Wednesday. Jupiter is the 2nd brightest planet. But it is now near sunset and visible only in bright twilight. Bright twilight skies make Jupiter more difficult to find. But Jupiter is still visible to the naked eye very close to sunset. And Wednesday? It is fainter than Jupiter (though still brighter than most stars). But it is near sunset. Shortly after sunset, start looking for the pair on the western horizon. You need clear skies and an unobstructed western view to catch them. A telescope should help. They disappear only 30 minutes after sunset. So, when the sun sets, the clock chimes.

tuesday, now the 5th planet in the evening sky, was easy to spot earlier this week because it’s not far from the Moon in our sky’s dome. A bright red light near the moon on Tuesday evening, March 28, 2023. Mars is bright. It is brighter than most stars. And it is clearly red. Even after the sun goes away, you can still spot Mars by its color and by the fact that it doesn’t shine like stars.

Artemis 2’s Canadian astronaut got their moon mission seat with ‘potato salad’



It took four years of negotations for Canada to get a seat on NASA’s upcoming moon mission.

That mission, Artemis 2, will send a Canadian and three Americans around the moon no sooner than November 2024. The Canadian seat comes courtesy of a big contribution to NASA’s Artemis program: Canadarm3, a robotic arm that will service the planned Gateway moon-orbiting space station. (The identities of the Artemis 2 crewmembers are currently unknown but will be revealed on Monday, April 3, in a live NASA event that you can watch here at

Canadarm3 was announced in 2019 as part of a big push in Canadian federal government circles to reprioritize space exploration. The government pledged US $1.56 billion USD in space spending over 24 years ($2.05 billion CAD under 2019 exchange rates). That’s $65 million USD a year, a fairly significant amount for a space agency that specializes in niche projects.

Much of that Canadian Space Agency (CSA) money was for Canadarm3, but some was also earmarked for a business incubator known as the Lunar Exploration Acceleration Program (LEAP). Other support went to food and health tech development contests designed to assist future deep space astronauts.


Getting all that funding and securing a seat on Artemis 2, however, took four years of behind-the-scenes negotiations. To introduce what happened, let’s talk about something that may not sound all that space-y at first: potato salad.

Canada is a powerful tech specialist that has been supplying highly capable space robotics since 1981 — Canadarm for the space shuttle program; Canadarm2 for the International Space Station (ISS), along with a “handy robot” named Dextre; and Canadarm3, which will be built by the company MDA. These are all crucial tools used for applications such as spacewalking, satellite repairs and space station servicing.

Ken Podwalski, a senior CSA official involved with the Artemis 2 and Gateway negotiations, likens the reputation of Canada’s space robotics to the dinner guest who comes armed with a divine side dish: “People look at Canada and say, ‘Canada, you guys make the best potato salad, bar none. It’s the best potato salad you can get. Nobody does it like you.'”

His confidence comes from decades of space experience. NASA’s Hubble Space Telescope, for example, would not be running today without Canadarm, which was used on five space shuttle servicing missions to the iconic observatory from 1993 to 2009. Nor would the ISS exist in its current form without Canadarm2, which berths cargo ships, assists in construction and even starred in a spectacular 2007 emergency spacewalk to fix a torn ISS solar panel.

But in 2015, when the future of the ISS collaboration was being discussed within Canada, the U.S. and other nations, there were lots of questions about what would happen next. Canada was just changing over from a Conservative to a Liberal government for the first time in nearly a decade, following the 2015 election.

The U.S. was on the eve of the 2016 election, which brought in a new presidential administration as well. Numerous ideas were batted about concerning the direction of NASA’s human spaceflight program over the coming years. Would the agency work toward a crewed visit to an asteroid? A moon mission? How quickly and with whom? And within Canada, no space plan for government spending direction had been formulated for many years, making roadmaps similarly uncertain — until a high-level strategy document came out in 2019.

The multinational space groups Canada is a part of all agreed on one thing, Podwalski said: Mars was the ultimate destination. The question simply came down to which pathway to take. The CSA created its own planning group that used the ISS agreements as a starting point. Gateway, though changing design and scope periodically, was a solid enough target to plan discussions with NASA during the 2015 to 2018 negotiations, he said.

“We were going through this quite intensive time. We were doing presentations with the partners and trying to understand what the right fit was,” Podwalski recalled. “We were [also] doing presentations with our government, trying to make sure that we’re taking the right approach.”

Building the new Canadarm3 was established as the primary aim. Podwalski, citing what he calls the “potato salad speech” he brings out in such planning meetings, said he always told people that focus was essential.

“Everybody expects Canada to bring the potato salad,” he said. “The potato salad gets you in the door, no problem … and it doesn’t stop you from bringing anything else. You’re now a part of the party. Now’s a good time to bring up other things.”

He thus urged his collaborators to deprioritize expensive and newer work that Canada could undertake, such as space modules or large rovers. But they also sought other avenues where modest investments could have a powerful impact and involve many smaller companies in related industries to space. Through these conversations, a mini moon rover (announced in 2021), a lunar utility vehicle (announced in the Canadian federal budget on March 28) and the CSA LEAP incubator program (renewed in the 2023 federal budget) all eventually came to be as well.

Canadarm3 was also designed to align with the priorities of the Canadian government. Serving remote communities in the north, especially Indigenous groups, through spinoff medical technology? Check. Continuing to grow Canada’s artificial intelligence community, a key tech direction for the country? Another big check, as Canadarm3 will be autonomously operating without astronaut crews nearby for at least 11 months a year. Preparing for Mars? Absolutely, as the artificial intelligence and robotics will also be beneficial on a more faraway planet, Podwalski said.

Podwalski emphasized how important it was to stay flexible through the negotiations, which extended through several U.S. election and Canadian cycles across 2015 to 2018, not to mention policy changes in the European Space Agency, the Japan Aerospace Exploration Agency and other partners.

“It is difficult to pull together these multibillion-dollar programs and get all these partners with all their own agendas about what they want to do in space, what technologies they want to develop and what they want to do with their industry,” he said.

Formulations also will continue to change on the key hardware, he emphasized, and negotiations are always undertaken with that flexibility in mind. For example, he said, it’s possible that Gateway may alter again after SpaceX‘s Starship achieves its first spaceflight as soon as this month, given that Starship could carry a considerable amount of cargo to lunar realms.

But for Canada, the benefits from Canadarm3’s “potato salad” approach have been considerable so far. The Artemis 2 seat, when offered by NASA, met the CSA’s goal of having an early moon mission with an astronaut on board to build industry and scientific momentum for other moon ventures, Podwalski said.

So far, NASA has also promised a long-duration Gateway mission to Canada sometime in the future. Other astronaut lunar journeys may come, including a landing mission, in negotiations down the road.

The ISS journey will continue alongside Artemis, too. Canada last month committed to extending its ISS participation to 2030 alongside other partners who agreed to that last year, most crucially NASA. (Russia has said it aims to exit the ISS partnership sometime after 2024.) Canada will also fly an astronaut to the ISS again in 2024 or 2025, the Canadian federal budget confirmed a few days ago.

Podwalski urged the community to keep watching for new announcements. “We’re a partner in good standing,” he said of the ISS and Artemis consortiums. “We’re part of the initial [moon] foray; we’re part of the trailblazers. It really does position Canada in a good way.”
