I am curious to know if there have been any controlled scientific experiments
 to prove or disprove astrological claims?

 If you find examples of such experiments can you let me know what the outcome 
 was?

 Kind regards

 Mongolia

Greetings Mongolia:

There is a lot of scientific research out there on various aspects of
astrological influces yet you will need to examine various links to
determine your own summation of research presented.  I didn't include
some of the sites I found because they seemed much less credible than
others.  I am offering below the links I believe contain the most
merit for your studies.

Astrological Research and the concept of similarity by Dr. Peter
Niehenke: Lecture held at the 10TH INTERNATIONAL RESEARCH CONFERENCE
ON ASTROLOGY by: The Astrological Association & URANIA TRUST, London
(9th and 10th November 1996):
"Most of the numerous master theses and dissertation papers dealing
with an empirical investigation of astrological claims, again and
again lead to the same result: no support for the astrological
hypothesis."
From http://www.mandala.be/declination/niehenke.htm

An interesting paper I found titled "Nonuniform distribution of the
ecliptical longitudes of sun and moon at the birthdays of top
scientists" is noted to have been in "Psychological Reports (VOL.85,
35-40, 1999)."  The link is at
http://www.ping.be/jvwit/testingastrology.html and the Introduction
reads in part "Logically, the horoscope cannot describe or fix all
aspects of life history. This follows from the fact that every human
has a lot of astrological twins, with whom he/she shares the same
horoscope, but clearly not the same fate. The best we can expect is a
partial correlation between certain aspect of life histories and
certain elements of the horoscope.  In order to render hypothetical
astrological correlations as prominent as possible, it is important to
consider extravagant populations that show strong overall
homogeneity."

Noted psychiatrist Carl Jung's observations and comments concerning
your query at http://koti.mbnet.fi/neptunia/jungast3.htm note "A
Frenchman, Paul Flambart, made an attempt to verify certain irrational
statements. He has done some scientific research work in connection
with the so-called aerial trigone: If the whole zodiac is designed in
sections of a circle, then the three points, the months represented by
Gemini, Libra, and Aquarius, form the aerial trigon. These are
air-signs, and air means mind or spirit. The old saying was that one
born under these signs was apt to be spiritual or intellectual; that
quality was given him at birth. So Flambart took one hundred
nativities of men remarkable for their intelligence, and he found
that, though the birth-dates were everywhere on the circle, there was
an extraordinary accumulation on each point of the trigon, so one
could say that the majority of such nativities were associated with
the corners of the aerial trigon, with intelligence."

To mongolia-ga, Astrology has been around for a long time. Its
mentioned in the Bible at Daniel 2;27, 4;7, 5;7, and 5;11, If you
consider the bible as the word of God, astrology is not regarded in a
good light. at Daniel 2;27, they were included with conjurers and
magic practising priests and were unable to explain the dream that
King Nebuchadnezzar had about the image with a head of gold and feet
of mixed iron and clay. Daniel explained it to the King but the
astrologers could not. They certainly did not have God`s approval,
whereas Daniel did, as only God had the power to rescue him from the
lions den.
Again, in Matthew 2, verses 1, 7 and 16, the people mentioned in the
bible , who we think of as wise men, were in fact astrologers, who
studied the heavens for signs. Verse 16 says that Herod was outwitted
by the astrologers, flew into a rage and ordered that all baby boys
from two years and under were to be killed. The reason for the two
year time frame was that the astrologers had been journeying for two
years to get to Bethlehem. Satan the devil was behind the scheme
because he wanted Jesus killed by the authorities. This was why Joseph
and Mary fled to Egypt to save Jesus` life. This is recorded at
Matthew 2;13 [Jehovah`s angel appeared in a dream to Joseph, saying,
"Get up, take the young child and it`s mother, and flee into Egypt,
and stay there until I give you word, for Herod is about to search for
the young child to destroy it. Verses 14, 15 describe how joseph
stayed in Egypt until Herod died, and this fulfilled a prophecy by the
prophet Hosea, and recorded at Hosea 11;1.
So if you seek God`s favour, consider his attitude to astrologers as
shown in Deuteronomy 18; 9 to 13. " There should not be found in you
anyone who passes his children through fire[ worshippers of Baal]
anyone who employs divination, practices magic [ common these days]
looks for omens, or a sorcerere, or binds with a spell [ hypnotists]  
or who consults spirit mediums [ again common in magazines] or anyone
who inquires of the dead . For anyone doing these things is detestable
to Jehovah [God`s name Psalm 83;18 Exodus 6;3]. One final point. God
is not against knowing astronomy, the study of the heavens, for
scientific purposes. Isaiah 40;22 describes the circle of the earth
and Job 26;7 says He is stretching out the north over the empty place,
hanging the earth upon nothing, What a perfect description of the
earth from space. How did Job know what the earth looked like from
space. It is only possible if he was inspired of God. 2 Timothy 3;16.
