More detail on how the Moon’s shadow will sweep over the Earth on March 20. The picture, from Astronomical Calendar 2015, shows the situation at 9:30 Universal (Greenwich) Time. The gray tapering cone represents the umbra or total shadow (not really visible when out in space). The small dark ellipse is the umbra’s footprint on Earth’s surface at this moment; for people within it, the Sun is totally covered. The huge penumbra, or partial shadow, becomes gradually less dense toward its outer edge, as more of the Sun is visible. Curves show this penumbra’s limit at times before and after.
Here is a closer view at the same time. Totality will reach the Faroe Islands (emphasized in white) at 9:41 and last about 2 minutes.
During those precious seconds (if the low Sun isn’t behind fog or cloud) we’ll whip our protective goggles away from our eyes and revel in the sight of the eerie and glorious corona exploding from behind the black circle of the Moon.
The Faroese joke is that their dry season is February, because in that month it can rain for only twenty-eight days.
Nevertheless, we sail in hope.
