June 10, 2021: From Eastern Canada to Eastern Russia, the moon incompletely blocks the sun. A ring of sunlight is visible around the new moon, making an annular or ring eclipse. From New England, a partial eclipse is visible as the sun rises. The maximum eclipse visible from US locations is less than 80%.

On the morning of June 10, 2021, the moon shadow initially touches the ground in Canada, near Lake Superior. The ring eclipse is occurring as the sun rises from the Lake Superior region. From Toronto, the sun is 80% eclipsed at sunrise. At this city the eclipse ends at 6:37 a.m. EDT.
The maximum eclipse shadow races eastward across Hudson Bay and Baffin Island. The partial eclipse shadow spreads away from the region of maximum eclipse. New Englanders see a partial eclipse. Montpelier, Vermont sees the sun eclipsed as it rises at 5:06 a.m. EDT. Maximum eclipse (77%) occurs at 5:36 a.m. and the eclipse ends 6:36 a.m. CDT. From Boston, nearly 73% of the sun is covered.
Farther from the region where the annular occurs, the moon covers less of the sun: Detroit, 63%; Cleveland, 64%; Chicago, 30%; Philadelphia, 73%; and Minneapolis, 26%.
For cities still farther away: Atlanta, less than 1%, Charlotte, 19%; Greenville, 10%; Sioux Falls, 2%; Nashville, 1%.
The ring eclipse shadow continues to zoom across northeastern Canada, northern Greenland, the North Pole, and Arctic Ocean, leaving the land in eastern Russia.
Partial eclipses are visible across northern Europe and into western Russia.
Do not look at the sun directly anytime. The interest of the eclipse may entice observers to look at it directly. Eclipse viewers or eclipse glasses that shield out the sun’s direct rays can be used.
Project the eclipsed sun image with tiny holes poked into paper plates; use a straw hat or a kitchen colander .
The overlapping branches and leaves create tiny holes for sunlight to make tiny eclipses on the ground.
Images can be projected through telescopes on screens to view the eclipse.
