Rise and set times of the sun and
moon for today via the USNO on-line computer.
For the USNO complete sun and moon data for one day, click
the logo.
Needed data:
longitude east 5 degrees, latitude north 52 degrees,
time zone 1 hour east of Greenwich, location Netherlands.
Time zone 2 hour east of Greenwich for summer time.
The new moon rises in the east with the sun, the first quarter moon rises around noon, the
full moon rises at sunset, and the third quarter mon rises around midnight.
The new moon is standing at midday at her highest point in the south.
First quarter moon is standing in the afternoon at her highest point in the south.
Full moon is standing at midnight at her highest point in the south.
Last quarter moon is standing in the morning at her highest point in the south.
The new moon sets in west with the sun, the first quarter moon sets around midnight, the
full moon sets at sundown, and the third quarter mon sets around noon.
Generally speaking the moon will be high in the sky when the sun is low (i.e. northern
hemisphere winter) and vise versa.

The moon: climate and landscape
On the moon air and water are missing. By daylight it is there
constantly dry, sunny and very hot with maximum temperatures until 120 degrees Celsius.
The night is cold and clear with minimum temperatures until 150 degrees Celsius beneath
zero. On the moon we see many structures, such as plains, craters, mountains and valleys.
A thick layer of moondust covers large parts of the surface. More about this.
The dates and types of eclipses during 2011 are as follows.
2011 Jan 04: Partial Solar Eclipse.
Observers in Europe, northern Africa, the Middle East and parts of Asia can
witness a partial eclipse of the sun. The penumbral shadow first touches Earth's surface
in northern Algeria at 06:40 UT. As the shadow travels east, Western Europe will be
treated to a partial eclipse at sunrise. Greatest eclipse occurs at 08:50 UT in
northern Sweden where the eclipse in the horizon will have a magnitude of 0.86 (86%),
producing a fantastic crescent sunrise. Most of northern Africa, the Middle East and
Central Asia also lie in the penumbra's path. A sunset eclipse will be visible from
central Russia, Kazakhstan, Mongolia and northwest China. The partial eclipse ends when
the penumbra leaves Earth at 11:00 UT.

2011 Jun 01: Partial Solar Eclipse.
The event is only visible from high latitudes in the Northern Hemisphere. The
eclipse begins at sunrise in Siberia and northern China where the penumbral shadow first
touches Earth at 19:25 UT. Two hours later, greatest eclipse occurs at 21:16 UT. At that
time, an eclipse of magnitude 0.60 will be visible from the Arctic coast of western
Siberia as the midnight Sun skirts the northern horizon. Although most of Alaska and
northern Canada will witness the partial eclipse, the southern limit of the penumbra falls
along a curve from south of Fairbanks to central New Brunswick and Nova Scotia. Reykjavik,
Iceland receives a 0.46 magnitude eclipse just before sunset. Northern most Norway, Sweden
and Finland also get a midnight Sun eclipse with the event hanging above the northern
horizon. The partial eclipse ends at 23:07 UT when the penumbra leaves Earth just north of
Newfoundland in the Atlantic Ocean.

2011 Jun 15: Total Lunar Eclipse.
The entire event will be seen from the eastern half of Africa, the Middle East,
central Asia and western Australia. Observers throughout Europe will miss the early stages
of the eclipse because they occur before moonrise. Fortunately, totality will be seen
throughout the continent except for northern Scotland and northern Scandinavia. Eastern
Asia, eastern Australia, and New Zealand will miss the last stages of eclipse because they
occur after moonset. Again, the total phase will be seen from most of these regions. Even
observers in eastern Brazil, Uruguay and Argentina will witness totality. However, none of
the eclipse will be visible from North America. At mid-eclipse, the Moon is near the
zenith for observers from Reunion and Mauritius.
Partial eclipse begins: 18:23 UT. Total eclipse begins: 19:23 UT. Greatest eclipse: 20:13
UT. Total eclipse ends: 21:02 UT and Partial eclipse ends: 22:02 UT. A
total eclipse can be very magnificent.

2011 Jul 01: Partial Solar Eclipse.
This Southern Hemisphere event is visible from a small region in the Antarctic
Ocean, south of Africa. Such a remote and isolated event means that it may very well turn
out to be the solar eclipse that nobody sees. At greatest eclipse (08:38 UT), the
magnitude is just 0.10 (10%).

2011 Nov 25: Partial Solar Eclipse.
The event is visible from high latitudes in the Southern Hemisphere and includes
southern South Africa, Antarctica, Tasmania and most of New Zealand At the instant of
greatest eclipse (06:20) the eclipse magnitude is 0.91, making it the largest partial
eclipse of the year. The greatest lunar shadow will pass a region near the coast of
Antarctica (Southern Pacific).

2011 Dec 10: Total Lunar Eclipse.
The entire event is visible from Asia and Australia. For North Americans, the
eclipse is in progress as the Moon sets, with western observers favored by a larger
fraction of the eclipse before moonset. Observers throughout Europe and Africa will miss
the early eclipse phases because they occur before moonrise. None of the eclipse can be
seen from South America or Antarctica.
Partial eclipse begins: 12:46 UT. Total eclipse begins: 14:06 UT. Greatest eclipse: 14:32
UT. Total Eclipse ends: 14:57 UT and Partial eclipse ends: 16:18 UT.

Easter and whitsun.
Easter begins always on the first sunday after the first full moon in the spring and
whitsun on the sunday seven weeks later. Like in old times spring begins on 21 march. When
it is full moon and sunday on 21 march, then easter begins on the next sunday 28 march.
The rule just mentioned was made during the Council of Nicea in 325 AD to let the whole
christian church celebrate easter on the same day. Good friday is the friday before
easter and ascension day the thursday forty days after easter and ten days before whitsun.
For more about this, see the Internet
Mother's
day is the second sunday in may and Father's
day in the United States and many other countries is the third sunday
in June.
Thanksgiving
is celebrated on the second Monday of October in Canada (CA) and on the fourth Thursday of
November in the United States (US).
