Solar eclipse of March 20, 2015
From Wikipedia, the free encyclopedia
A total solar eclipse occurred on
Friday March 20, 2015. 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. A total
solar eclipse occurs when the
Moon's apparent diameter is
larger than the Sun's, blocking
all direct sunlight, turning day
into darkness. Totality occurs in a
narrow path across Earth's
surface, with the partial solar
eclipse visible over a surrounding
region thousands of kilometres
wide.
It had a magnitude of 1.045. The
longest duration of totality was 2
minutes and 47 seconds off the
coast of the Faroe Islands. It is
the last total solar eclipse visible
in Europe until the eclipse of
August 12, 2026.[1]
The only populated places
reachable by public land travel
from which the totality could be
seen were the Faroe Islands and
Svalbard.[2]

Viewing
The solar eclipse began at 08:30GMT in northwest Europe and moved towards
the northeast but still in northern Europe. It was most visible from the North
Atlantic and Arctic Oceans, Greenland, Iceland, Republic of Ireland, United
Kingdom, Faroe Islands, northern Norway and Murmansk Oblast. The shadow
began its pass off the south coast of Greenland. It then moved to the northeast,
passing between Iceland and the United Kingdom before moving over the
Faroe Islands and the northernmost islands of Norway. The shadow of the
eclipse was visible in varying degrees all over continental Europe.[3] For
example, London experienced an 85% partial solar eclipse while points north of
the Faroe Islands in the Norwegian Sea saw a complete solar eclipse.[4]
The eclipse was observed at radio frequencies at the Metsähovi Radio
Observatory, Finland, where a near total eclipse was seen.[5]
Impact
The European Union has a solar power output of about 90 gigawatts and
production could have been temporarily decreased by up to 34 GW of that
dependent on the clarity of the sky. In actuality the dip was less than expected,
with a 13 GW drop in Germany happening due to overcast skies.[6] This was
the first time that an eclipse had a significant impact on the power system, and
the electricity sector took measures to mitigate the impact. The power gradient
(change in power) may be −400 MW/minute and +700 MW/minute. Places in
Netherlands, Belgium and Denmark may be 80% obscured.[7][8] Temperature
may decrease by 3 °C, and wind power may decrease as winds are reduced by
0.7 m/s.[9]
Coincidence of events
20 March 2015 was also the day of the March equinox (also known as the
spring or vernal equinox in the Northern Hemisphere). In addition, six
supermoons are expected for 2015. The supermoon on 20 March 2015 was the](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

The series started with partial solar eclipse on May 27, 933 AD, and reached an annular eclipse on August 11, 1059. It was a hybrid event for 3 dates: May 8, 1510, through May 29, 1546, and total eclipses from June 8, 1564, through March 30, 2033. The series ends at member 71 as a partial eclipse on July 7, 2195.
