Title: Solar eclipse, Friday 20 March
Post by: Glaurung on March 07, 2015, 12:03:29 PM
On Friday 20 March, there will be a solar eclipse. The path of totality runs the north Atlantic, between Iceland and Great Britain, so only the Faroes and Svalbard (Spitsbergen) get to see a total eclipse. It will be partial across the whole of Europe: 50-60% across the Mediterranean, and 85-95% in the UK. The Moon's shadow moves eastwards, so the maximum eclipse is around 09:00 GMT in Portugal and western Spain, about 09:30 GMT in the UK and Italy, and around 10:00 GMT in Sweden, Poland and Romania.

As ever with a solar eclipse, DO NOT LOOK AT THE SUN DIRECTLY, OR THROUGH A TELESCOPE (unless you want to lose your sight). If you want to observe the eclipse, you can use welders' goggles or equivalent, or project the image of the sun through a pinhole.

There's a lot more information on the NASA Eclipse website (http://eclipse.gsfc.nasa.gov/eclipse.html). For this particular eclipse, start at the 2011-2020 solar eclipse list (http://eclipse.gsfc.nasa.gov/SEdecade/SEdecade2011.html), scroll down to the list, and follow the links against "2015 March 20". The most useful link is probably one including a Google map (http://eclipse.gsfc.nasa.gov/SEgoogle/SEgoogle2001/SE2015Mar20Tgoogle.html) - you can click anywhere on the map, and get the times and other details for that location.

Getting up to see it is definitely recommended, though a partial eclipse is rather less impressive than a total one. I just hope the skies are clear.

Sad to report that Exilian's Norfolk observation point is totally overcast :(

Much the same here in Cambridge - one of my colleagues thought the clouds had just got thicker for a while. Now it's sunny here, of course :P

With solar eclipses, it's the last couple of percent of coverage, in the last minute or two before totality, that really makes the difference.
