Solar eclipse of June 10, 2021
An annular solar eclipse will occur on June 10, 2021, when the Moon will pass between Earth and the Sun, thereby partly obscuring the image of the Sun for a viewer on Earth. During the eclipse, the Moon's apparent diameter will be smaller than the Sun's, so it will block most of the Sun's light and cause the Sun to look like an annulus (ring). The annular eclipse will be visible from parts of northeastern Canada, Greenland, the Arctic Ocean (passing over the North Pole),[1] and the Russian Far East, whilst the eclipse will appear partial from a region thousands of kilometres wide, which includes northern and eastern North America, most of Europe, and northern Asia.
The annular eclipse will start at 09:55 for 3 minutes 37 seconds along the northern shore of Lake Superior in Ontario, Canada. The path of the antumbral shadow will then head across Hudson Bay through northwestern Quebec and the Hudson Strait to Baffin Island in Nunavut, where the town of Iqaluit will see 3 minutes and 5 seconds of annularity. After this, it will travel across Baffin Bay and along the northwestern coast of Greenland, where greatest eclipse will occur at 10:41:56 UT1 in Naires Strait for 3 minutes 51 seconds. The shadow will then cross Ellesmere Island and the Arctic Ocean, passing over the North Pole (which is located away from the central line of the eclipse but sees 2 minutes and 36 seconds of annularity), before heading south towards northeastern Siberia where the central line of annular eclipse ends at 11:29.[2] The greatest city on the Russian Far East in annular path, Srednekolymsk, will see 3 minutes and 35 seconds of annularity, the maximum will occur at 11:27:05 UT1.[3]
This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[4]
