Manitobans could be seeing an overnight light show thanks to a geomagnetic storm.

Gord Tulloch, the Vice President of the Royal Astronomical Society of Canada Winnipeg Centre is suggesting people head north, outside of Winnipeg to check out the northern lights.

"I think tonight is a good night and not tomorrow night, but the next two nights after that seem to be good nights to get outside and have a look," Tulloch says. "Keep the lights off, go somewhere safe."

The lights will begin once the sun sets, getting stronger near midnight. 

"I think the forecast has auroral activity starting fairly early in the evening, so you will probably be able to see it early in the evening and as the night wears on the auroral activity will probably get stronger."

Tulloch says because of Wednesday's cold temperatures, it will be important to assure you can stay warm.

He says to go far from lights, to places like Bird's Hill Park and Oak Hammock Marsh but avoid busy spots. Once arriving, Tulloch says to wait 10-15 minutes for your eyes to get used to the dark.

"To see colours and everything, you need to be fully dark-adapted."

He says the lights can often be seen, but it is not always caught by our eyes. He will be watching the lights tomorrow after his camera catches them.

"They are around all the time and we are just not outside all the time."

Photographer Nik Rave says a tripod will be necessary to get a photo that is not blurry.

"Go as low to the ground as possible, and then point it to the direction of interest.," Rave says. 

Rave says to use a manual camera and play with the shutter speed to find what works best.

Astronomy North Society and Aurora Forcast are both predicting that auroras will be visible overnight Wednesday.

Astronomy North says a G1-G2 Geomagnetic storm watch is being issued, meaning periods of active auroras could be seen. They expect lights to be at their strongest near midnight.

"An incoming gust of solar wind is expected to sweep past Earth late this afternoon or early evening," Astronomy North says. "Following impact, geomagnetic field conditions will become unsettled with active periods overnight."

They say there is an 85 per cent probability of light sightings in Churchhill overnight. People living in Northern Manitoba such as Gillam and Lynn Lake have been reporting seeing lights this week.

Aurora Forcast, based in the Yukon, is expecting to see intense aurora activity overnight.

"Active aurora possible with a slight chance of isolated minor auroral substorms and favourable conditions for major aurora activity," Aurora Forcast says.

Aurora Forcast says the storm's lingering effects could result in up to three days of northern light sightings.
