Next Meeting: Wednesday June 9th at 8:00pm on Zoom Solar Physics and the eclipse Lucie Green
An annular solar eclipse will occur on June 10, 2021. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. This eclipse is notable for the fact that the path of annularity will pass over the North Pole, the only such eclipse in 21st century.[1] While the eclipse is visible primarily in northern Canada, in Greenland and in north of Russian Far East, in the northeastern United States and Canada, the sun will be partially eclipsed at sunrise, which will be between 5 and 6 A.M. (EDT)

Lucie tells us: “My research focusses on the study of the evolution of the Sun’s magnetic field and how it drives solar activity that in turn leads to space weather at the Earth. My early work used new techniques to quantify the amount of magnetic helicity ejected by the Sun during events called coronal mass ejections. The results are important for many areas of solar physics including dynamo theory and the evolution of the global solar magnetic field. More recently, I have focussed on the question of whether or not flux ropes form in the lower solar atmosphere before coronal mass ejections. I am interested in how observations can be used to quantify the magnetic flux in these ropes so that we can better understand their evolution to an unstable and eruptive configuration. This work is important for developing the science that underpins space weather forecasting.
