A rare total solar eclipse in Antarctica this weekend (Saturday 4 December) is giving researchers a unique opportunity to learn more about how solar eclipses affect space weather. The next total eclipse in Antarctica will not be until 2039.
The total eclipse, which happens when the sun and moon are in line with the Earth, will only be visible in Antarctica, sweeping across the Ronne ice shelf and Ellsworth land, with the rest of Antarctica in partial shadow. The maximum eclipse will be at 0733 GMT.
John Law, Antarctic Atmospheric Scientist at Rothera station says:
“The team here are really excited about being able to witness the eclipse on Saturday morning. We will be setting our alarm clocks for the early hours, the maximum amount of Sun that will be hidden by the moon will be around 94% around 4am in the morning. During the summer, the sun never sets below the horizon so even at 4am we should see the effect of the eclipse. The sun will be low in the sky, hopefully just above the mountains of the Antarctic peninsula to the east of us. As a meteorologist I am normally a big fan of clouds but on this one occasion I’m hoping they stay away.”
