You could see the northern lights across most of Canada tonight, including in southern Ontario.
Here's what you need to know about the forecast and how to spot the aurora in the night sky!
A new northern lights forecast was released by NOAA for Wednesday, June 4, and it revealed that the northern lights are getting "more intense."
This comes as the aurora borealis has plunged south across Canada over the last week because of geomagnetic storms.
Usually, the northern lights are only visible in Canada from August to May, so this might be one of your last chances to see the aurora for a few months.
You could see a "more intense" aurora in Prince George, Calgary, Edmonton, Jasper, Whitehorse, Yellowknife, Regina, Saskatoon, Winnipeg, Churchill, and Moosonee.
The northern lights should be less intense tonight in Victoria, Nanaimo, Vancouver, Kelowna, Lethbridge, Thunder Bay, Timmins, Saguenay, and other cities.
NOAA's forecast also included a view line that shows how far south the aurora can be seen along the northern horizon.
Places within the view line include Toronto, the GTA, Ottawa, Montreal, Quebec City, Moncton, Saint John, Charlottetown and nearby areas.
Northern lights forecast map for June 4.NOAA
NOAA's northern lights forecast map has the brightness and location of the aurora as a green oval centred around Earth's magnetic pole.
When there's red, that means the aurora is expected to be "more intense."
So, the northern lights should be "more intense" across central parts of Canada, including B.C., Alberta, Saskatchewan, Manitoba and the territories.
But the aurora could still be visible as far south as southern Ontario and Quebec, along with parts of the Maritimes.
If you want to try to see the aurora tonight, the Canadian Space Agency has northern lights viewing tips.
Typically, the northern lights appear a few hours after sunset and become more intense around midnight.
You should find a place where there's little or no light pollution. Bright city lights will probably block the view if a less intense aurora is forecast in your area.
Then, once you've found a spot, look all around you because the northern lights can appear anywhere in the sky.
While green is the most common northern lights colour, the aurora can also be pink, red, blue and purple!
If you're in a place that's along the view line from this forecast, NOAA said that the northern lights will only be visible toward the northern horizon, not anywhere in the night sky.
