Tracking these dazzling celestial displays in the sky

The northern lights are projected to be visible in northern parts of Canada and the U.S. starting Sunday evening. While some regions will see full, colorful light streaks across the sky, others will be treated to mostly white or grey aurora borealis.

The Sun was at its maximum M3, or red, activity level this past week, a super peak that will make the magnetic field more sensitive and can cause energetic particles to enter the atmosphere.

But even when the skies aren’t full of the Northern Lights, though, there are plenty of other spectacular lights to spot.

If skies are clear, the International Space Station can also be seen between 30 miles (48 kilometers) and 200 miles (322 kilometers) above the Earth’s surface as it circles the planet 22 times a day at 17,500 mph.

Usually viewable at night, it’s been visible during the day over the last couple of days as part of its daily schedule. It’s making its way to the northern hemisphere to set up camp as a floating lab for more astronauts to visit.

In fact, the International Space Station passed over the Hong Kong International Airport. The passing ISS took advantage of a rare morning shadow.
