While these requirements are in stark contrast to the situation in 2017, when huge crowds gathered across North America to watch the total solar eclipse, said Dr. Reid, there is a silver lining: The pandemic prompted the Institute and colleagues at Discover the Universe, and Quebec-based astronomy education program, to send 20,000 eclipse viewers to people in and around the eclipse path, including in Nunavut, an area of ​​Canada whose population is mainly Inuit.

“Because they are in pretty remote locations, we wanted to make sure they had the material to watch them for,” said Julie Bolduc-Duval, executive director of Discover the Universe.

Dr. Reid added, “We’re in a situation in this pandemic where everyone is forced to stay home, but it actually helped bring everyone together on this one cause.”

Sudbury, Ontario is outside the annex but will still experience an 85 percent solar eclipse. Olathe MacIntyre, a research fellow at Space Place and the planetarium of the Science North Museum there, plans to contribute to a live stream of the solar eclipse on Thursday.

“It’s something we can share separately,” said Dr. MacIntyre.

Pat Smith works in Greenland for Polar Field Services, a National Science Foundation company that helps scientists and others plan expeditions to remote parts of the Arctic. Mr Smith plans to observe the solar eclipse at a location near Thule Air Base, the northernmost American military base about 700 miles from the Arctic Circle.

The location, North Mountain, is on the path of the annular solar eclipse that will last for nearly four minutes there, and visibility conditions are expected to be clear. Mr. Smith plans to take photos during the event.

In Russia, the solar eclipse will only be fully visible in some of the most remote regions of the vast country to the east, closer to Alaska than Moscow.
