August 21, 2017 a solar eclipse will occur over the entire
North American continent and parts of South America, the Pacific
and the Atlantic Ocean. The band of totality will cross the US
states Oregon, Idaho, Wyoming, Nebraska, Kansas, Missouri,
Illinois, Kentucky, Tennessee, Georgia, North and South Carolina.
When crossing the Oregon coastline, the Moon will cover the Sun
for about 2 minutes. The duration of totality will increase the
more the shadow moves eastward. At the point of maximum eclipse 50
miles west of Nashville there will occur 2 minutes and 40 seconds
of totality. Afterwards the duration will decrease, but when
reaching the East coast of South Carolina north of Charleston
there will still remain more than 2:30.
In north-western Europe, the eclipse will only be visible as a
partial eclipse, in the evening or at sunset, see map at right.
Only Iceland, Scotland and Ireland will see the eclipse from
beginning to end, in the the rest of the UK, Norway, the
Netherlands, Belgium, France, Spain and Portugal sunset will occur
before the end of the eclipse. In Germany, only in the extreme
north-west the beginning of the eclipse might be visible just at
sunset. In all regions east of the orange line in the map the
eclipse will be invisible.
During the entire eclipse, except the short
moment of totality, you must protect your eyes! Use certified
eclipse shades or eclipse glasses. Common sunglasses
are not sufficient by far! Binoculars
and telescopes must be equipped with proper filters to reduce
the light. Very important: Never use eclipse shades behind a
telescope ocular, because they will melt in the focused heat of
the lenses! If you are in the central zone, you do not need any
shades during totality, when the sky becomes completely dark as
night. You can observe the corona safely with your naked eyes
and even with binoculars or telescopes. But do not forget to put
filters and shades on before totality is over!
To remind you for putting the eclipse glasses off and on an
