david@jarnac.org ABSTRACT I was on
the way to my high school French Oral exam in October 1965 when I decided that
I wanted to begin a search for comets. Although I began the search on
December 17 that year, it was not until 1984-- 19 years or 917 hours at the
eyepiece later-- that I discovered my first comet. Twenty-one finds
later, I still feel that comets are more than just targets to be
catalogued. Thanks
in part to one co-discoveries, Shoemaker-Levy 9, we know more about the role
that comet collisions have played in the origin and evolution of life on this
planet. With the evolution of Pan-StARRS, the future of visual comet
finding will soon be relegated to the history of this important field of
endeavor. I am still searching for comets both visually and with an automated CCD program. This talk will be about my observing career and how my childhood fascination with the night sky led to a highly satisfying time under the night sky. GNEŞ

of the solar diameter observed about half a century ago, are thought to result
from big scale motions in the
solar photosphere. These motions
are highly variable in space and time and change amplitude according to the
physical aspects of turbulence, magnetic field and rotation. Standard solar
models (SSM) obtained directly from the
integration of the linear differential equations describing these motions
with respect to turbulence, agree very well with the observed solar resonant
periods. On the other hand, inclusion of rotation and magnetic field in the SSM
split the frequencies symmetrically. Similar
to the p-modes encountered in the Earth quake waves, the observed solar
pulsations contain quantitative information about the structure of the solar
photosphere. Therefore, the geophysical inverse model is employed also in
Helio-seismology in order to estimate density, temperature and pressure inside
the Sun, from the observed acoustic p-modes of 5 minutes periodicity. In this
work examples obtained by the two methods will be presented and compared both
with the standard solar models and observations. Dnya'ya En Yakn

Tombaugh, discoverer of Pluto and a lifelong AAVSO friend, lived in Las Cruces
for the last 50 years of his life; his family still lives here. During his
search for trans-Saturnian planets he discovered what he thought was a nova in
outburst March 23, 1931. Although he reported it to his superior at the time,
news of the discovery remained buried in the plate archive at Lowell
Observatory until I found it while doing research for his biography. A search
of the plate archives at Harvard subsequently revealed 9 other outbursts of
what was apparently a cataclysmic variable of high galactic latitude. Now named
TV Corvi, the star was first visually observed in outburst on March 23, 1990. On
February 2, 2005, I caught the star rising in the southeast and climbing rapidly
in magnitude. The movie consists of several images taken throughout that

david@jarnac.org ABSTRACT The idea of watching a point of light brighten and fade over a specific period of time is not always an "easy sell"-- there are some very good amateur astronomers who have embraced the planets, comets, and deep sky observing while leaving variables alone. Like fine wines, variable star observing can be an aquired taste. Fortunately, over the decades, some people have dedicated their careers and lives to making the field accessible to the larger community of lovers of the stars. This presentation celebrates the work of two of these championbs-- William Tyler Olcott and Janet Mattei, two mentors who transformed variable star observing into a field that touches the hearts of their generations. They both combined knowledge and enthusiasm for variables with an uncanny way of reaching out to people. Variable stars would not be the field it is today were it not for the efforts of these very special astronomers. Işk

it is not possible for people, who live in or near cities, to have a view of
the universe. Since the population of the urban areas increased, outdoor
illumination has been considered to be necessary which now ends up with the
consequences of urban sky glow.
The misuse of light doesnt increase nighttime security. The excess
light in the sky cause light pollution and it doesnt only obstruct the night
sky view but also threatens the nature. Since
astronomic studies should be done away from air pollution and urban sky glow
resources, the sky glow which illuminates the night sky is a threat to amateur
and professional astronomy. Understanding
the concept of light pollution is very important to control it. Some of the
precautions to be considered are using night lighting only when it is
necessary, directing the light downward in order to prevent illuminating the
sky, using low pressure sodium light sources if color rendering index is not
very important and avoiding development near existing observatories. BARN DOOR VE BENZERİ MONTAJ

(AAVSO) is a worldwide, nonprofit, scientific and educational organization of
amateur and professional astronomers who are interested in variable stars. Its
purpose is to coordinate, collect, evaluate, analyze, publish, and archive
variable star observations made largely by amateur astronomers, and to make
these observations available to professional astronomers, researchers, and
educators. The AAVSO was founded in 1911 at Harvard College Observatory to
coordinate variable star observations made largely by amateur astronomers. In
1954, the AAVSO became an independent, private research organization. Today
with members in more than 40 countries, over 10 million observations to date,
and headquarters
in Cambridge, Massachusetts, USA, it is the worlds largest association of
variable star observers in existence. Membership in the AAVSO is
open to anyone interested in variable stars and in contributing to the support
of valuable research. Since professional astronomers have neither the time nor
the telescopes needed to gather data on the brightness changes of thousands of
variables, amateurs have been making a real and useful contribution
to science by observing variable stars and submitting their observations
to the AAVSO International Database. Observations of most types of variable
stars are coordinated and published by the Director and the technical staff at AAVSO
headquarters. Observing for certain types of stars is coordinated outside of
AAVSO headquarters, under the authority of the AAVSO director. M.. 4500-540 Yllar

himenali@statestreet.com Abstract It might be surprising to many people that
astronomy is unique among the sciences in which amateurs can and do play an
important role. Amateur astronomers frequently and increasingly make valuable
contributions to astronomical research. While professionals are typically
absorbed in conducting specialized research, amateurs can go for time-consuming
activities such as comet and asteroid hunting, variable star observing, novae
and supernovae searching, making lunar and planetary observations and more! In
addition to that, observing time at the major observatories is limited and it
is not that easy to come by. This leaves open areas in which a dedicated
amateur can make a significant contribution. Some of the tasks only
professional astronomers were able to perform in most of the 20th century, are
being done by amateurs today almost to the same degree as professionals.
Commercially available affordable equipments, not having observing time
restriction as in professional observatories and being scattered around the
globe geographically are some of the factors that are making the amateur
contributions soar. It is what we call Backyard Astronomy after all. GNEŞ

of the physical changes in the 30 % outermost convective solar layer with the
use equations of magneto-hydrodynamics (MHD) for both linear and non-linear
cases. Maple 8 was used for studying the changes in density, pressure,
temperature and magnetic field with respect to time and radius. The first order
perturbation approximation was used in MHD equations while we examine the
linear case. For the non linear case, the Sun was accepted as a spherically
symmetric star and the analytical solutions of these equations were obtained.
Hydrostatics equilibrium state was taken as a Standard Solar Model (SSM)

measured by the occultations. In order to observe an occultation of a star by
the asteroid, the first step is to determine the time of its passage in front
of a star on the sky. This time can be calculated using WinOccult Ver. 3.0
software. In this method the duration of the occultation of a star is measured.
Then the diameter of the asteroid is calculated using the its distance and the
orbital velocity. Occultation technique gives very precise results for the
spherical shape asteroids. Results obtained from the occultation method can be
used the calibration of the other indirect methods such as thermal radiometry. Astronomy

Archaeoastronomical Heritage of the European Society
for Astronomy in Culture, e-posta: magda@aira.astro.ro ABSTRACT In the
entire world there are proofs of astronomical culture, from the famous
Stonehenge or Carnac, up to tapestries (Bayeux), heraldic symbols, sundials,
old observatories or manuscripts. All of them preserve in stone, wood,
ceramics, metal or paper the knowledge gathered throughout the centuries
concerning the sky, the cosmos. They
are spread all over the world. Sometimes they are well catalogued, researched
or preserved. Nevertheless, very often they are very little known and very
badly preserved, sometimes about to disappear. You want to find out where there
is a sundial from a certain epoch and you do not know how. You want to know when
some phenomena were recorded for the first time and researches to this effect
are difficult. You want to support the restoration of a sanctuary, also used
for astronomical purposes, and you do not have enough proofs to motivate the
sometimes very high expenses required by such an operation. A data
bank in which all this information should be gathered, an electronic library of
international size, would be the exact thing to facilitate research, to support
the conservation of the art, science and history monuments, which together make
up the thesaurus of civilization on this planet. This
is shortly the reason why a new working group The Archaeoastronomical
Heritage (http://www.archeoastronomy.org/)
was set up. Everyone interested in identifying and preserving this rich
heritage is invited to contribute to its activity. BASİT

scientific research is conducted to construct an equation relating time and
date variables using the data obtained from periodic movements of some stars. The periodic movements of the stars have been examined carefully with a software
program named Starry Night Pro that gives the accurate locations of the stars in picture. Using the pictures of stars of a certain time and
date, I have found the systematic variation in the location of stars. I have
transformed the variation into equation form. This equation helps us to
determine the time if the date is
given and vice
versa. This systematic variation is caused of the
difference between the real and accepted rotation period of the Earth. In other
words its accepted that the earth spins around its axis once in 24 hours but
in fact the real period is 23 hours 56 minutes. This time difference causes a deviation in the
location of stars. Measuring the deviations for many times helped us to find
the relationship between time and date. UZAY

and techniques, astronomical observations are carried out in each area of
electromagnetic spectrum. Radio astronomy is a technique, by which, radio waves
emitting from astronomical objects are received, recorded, and assessed. The first radio observations in Turkey were
carried out in TUBITAK MAM(Marmara Research Center) on 1996-97, by MRT-2
(Marmara Radio Telescope-2) having 2m dish, which were bought from Kharov Radio
Astronomy Institute with the help of UNIDO. Later on, this telescope was
donated to Erciyes University, Astronomy and Space Sciences Department . With
the Radio Telescope which was re-constructed with the help of the 5m dishes
taken from Turkish Telecom in 2002, the neutral hydrogen observation in our
galaxy are planning. TRKİYE'DE 29 MART 2006 TAM GNEŞ TUTULMASI Nilda

in education are getting bigger and day after day reformer solutions are taking
part in education ways. To improve peoples interests and abilities in Main
Sciences a reformer solution having been prepared since a few years ago. That
subject is about using movies in science. Combining Cinema and Education
reveals impressive results. Also using cinema in Education of Astronomy and
Space Sciences gives perfect results. Our goal is using the scenes have taken
from movies that use astronomy and space subjects, suggesting a new kind of
educating Astronomy and Space Sciences. A "Physics in Films" class at
Central Florida University, taught by researchers Costas Efthimiou and Ralph
Llewellyn, has drawn more than 2,000 students since its first offering in 2002.
These educators firstly used the main physical laws. And they showed other
scientists a new way of education. The subjects; understand the universe,
life on the other planets, danger from space, and space travel in movies
can be great sources to study Astronomy and Space Sciences. Critiques and
reviews of those movies can improve students interests and abilities in
Astronomy and Space Subjects. As a result we want to share that way of education
with our colleagues. Gezegensel

AH Vir has been performed with published minimum times and new minimum times
which obtained at Ankara University Observatoy. In order to designate the
charactristic of period variation, an O-C graph formed. O-C graph shows a
period increase with cyclic variation. Under the assumption of conservation of the total angular momentum, the period increase
can be atrtributed to mass transfer from less massive to the massive one.
Cyclic variation can be attributed to light-time effect due to presence of
third body in the system. The related physical parameters derived in this
assumption. Keywords: AH Vir, eclipsing binary stars, period

The astronomy departments of the universities in
Turkey have made great effort in the last 50 years to increase the concern and
sympathy of the public in the field of astronomy and in science as well.
Publishing some periodicals and organizing summer schools are main activities
among these. The staff and the students of the Astronomy Department of Ege
University have assumed a leading role during the last 14 years and trained
hundreds of people. 50% of the participants of the organized summer schools are
between 18-50 years of age and this fact indicates that they are well able to
continue their work themselves. Some of the people who followed these
activities have started working on various topics with their own telescopes.
Some of these works have already been published in various magazines. 29 MART 2006 TAM

magnificant natural event so that people can see maybe only once in their
lifetimes if they do not move to another place. Our country will witness again
a total solar eclipse on 29 March 2006 after the 11 August 1999 eclipse. This
eclipse will be visible within a zone starting from western Mediterranean to
eastern Black Sea regions during almost 4 minutes. On the other hand, TUBITAK
National Observatory of Turkey lies within the zone of this totality. This work
include the specifications of 29 March 2006 total solar eclipse, contact times,
meteorological data, public organizations and observational techniques.
Preparations have already begun in Antalya and at the National Observatory to
utilize this rare fascinating event. APOD:

Observator, ABD, Amatr Astronom ABSTRACT Although I didn't meet Janet until the last year of her life, we immediately became good friends-- not so much for her love of astronomy but for her almost equal passion for flowers. As David showed her our observatory complex, I shared her amazement as she stopped over and over again to admire the diversity of natural flowers in our desert home, and she told me of her interest in doing a project-- some day-- relating her two loves of flowers and the universe. In her honor, I offer a look at the amazing coincidences that atoms and Nature can come up with-- a dandelion on Earth and Scorpius in the sky, a flower blooming for only a day to remind us of a long-gone nova in Messier 80, and other tiny flower designs that mimic some of the vast structures of distant galaxies.

yenalogmen@yahoo.com ABSTRACT Ive been doing observations for four years with
Meade ETX125 telescope. Up to now, Ive taken Astronomical League Lunar Club
and Double Star Club certificates by doing Moon and Double Star observations.
Currently Im observing Messier objects for the Messier Club certificate. At
the same time, Im observing Bright Lunar Rays for ALPO and Variable stars for
AAVSO. I do observations about three nights a week. My observation site is the
observatory Ive built in my houses backyard, Green Island Observatory. The
need for building the observatory has risen due to the difficulties faced with
when carrying all the stuff each time needed for the observation. The
observatory, which was built between the July 2004 and February 2005, is
situated in Geitkale, Northern Cyprus. The observatory is formed from
cylindrical concrete walls and a wooden dome situated on its top. The dome,
which is mounted on a U-joist ray, is moved manually. Im planning to have a
bigger aperture telescope and a CCD camera. In order to prevent the small
vibrations caused by my movements while observing, j-bolts are fixed in an
isolated concrete part in the centre of the floor. The telescope will be
mounted on a pier, which will be set on j-bolts. My future plans
are, to get more educated by having the advanced university certificates in
Astronomy and to develop observational experiences and to do observations to
contribute the Astronomy. Değişen

Gzlemevi, Akdeniz niversitesi Yerleşkesi, 07058, Antalya e-posta: aslan@tug.tug.tubitak.gov.tr Abstract The number of amateur
astronomers in Turkey is increasing rapidly in recent years. Many of them have
their own telescopes equiped with detectors such as a CCD camera. We know that
beautiful pictures are secured with these instruments. But it is now time to
turn these hobies into scientific observations, mainly concetrating on variable
stars. Our amateur astronomers should come together under a national
association which helps its members with coordination of observations, with
astronomical tools to be used in the reductions, and with assessing the
accuracy of their observations. This national body should maintain a database
for the benefit of its members and for the use of professional astronomers. |
