This is the first issue of ILBA in the XXI century, and the editors hope thatby its frequency and content it will continue to be useful to all those engaged in space research in the Balkan countries, and possibly wider.
While you are reading this, you are certainly aware that a big change has occurred: the previous issues were prepared as simple txt files, while this issue is a doc file.This is a small step in bringing ILBA to a better technical level.
Year 2001 has started with a total lunar eclipse, visiblefrom the Balkans on January 9.It was observed,visually and photographically,by amateurs from different locations in Serbia.Unfortunately,the weather was nearly everywhere partially cloudy. The amateur groups active in the city of Valjevo have managed to obtain excellent photographs, and estimate the brightness of the eclipse on the Danjon scale. Their result is L=2-3,but nearer to 2; the observers admit that theresult is not as good as it could have been because of clouds, dissipating around the moment of totality.For details contact Mr. Branislav Savic at email@example.com.
In the lastissue of
ILBA, we have announced a forthcoming meeting in Greece - the Fifth
Hellenic Astronomy Conference, which will be held on the island of Crete in
September of this year. In the meantime, the conference web has been
somewhat changed, so it is now as follows: http://astrophysics.
physics. uoc. gr/conf/
. The invited lecturers and the
conference sections are now known.
Dr. Magda Stavinischi has informed the editors about a new web
address : http://roastro. astro. ro/
.It is maintained at the Institute of Astronomy in Bucharest, and gives
you access to various data about space science in Romania.
the editors of ILBA have received and interesting offer
from the USA. Mr. Sasha Skerlich, of Serbian origin but living in Las
Vegas, has offered to develop a web site on which he could post issues of
ILBA and other materials related to astronomy and related sciences in the
Balkan region.His offer isaccepted
with thanks, and correspondence is under way .
At the University of Belgrade, the Astronomy departement has its home page. The address of the english translation of this internet presentation is:
One of the ideas advanced at the meeting in Belogradchik was that
space sientists from the Balkan countries should develop joint projects
based, as much as possible, on existing equipement and facilities.A
practical proposal along these lines has recently arrived from Dr. B.
kiev. ua.The idea of Dr.Zhilyaev is to launch a project in observational solar
physics aimed at young astronomers from the Balkans. The project could last
up to three years, and it would use the existing horizontal solar telescope
(HST) at the observatory on Mt. Tereskol in northern Caucasus . The altitude
of the observatory is 3100m.
The parameters of the instrument are: D = 65
cm, F=168 cm. It is
equiped with a five chamber spectrograph with the size of the spectra
20x25 cm. The grating has 600 lines per milimeter, the instrumental contour
is 18 mA in the spectrum of fourth order at 633 nm.The detector is a 768
x 512 CCT ST-1 with pixels of 9 micrometers. Details can be obtained from
Dr. Alexey Andrienko at the addresses: (olexa@mao.
olexa@burbon. nalnet. ru ) andthe local
project coordinator is Dr. Nikolay V. Karpov(karpov@mao.
kiev. ua ).
At the turn of the centuries,two of ourcollegues have died: one in Macedonia and the other one in Bulgaria. Their obituaries, written by close collaborators and friends are included in this issue of ILBA.
basic idea of ILBA is to represent a channel through which all those
interested can gain information on space research in the Balkan region.
Continuing with this practice, in the follow up comes a list of
recent publications by authors from the Balkans. It is certainly
incomplete, but the only way which can assure its completeness is letting
the editors know about your results.So please - write tothe editors,
sending an e-mail is certainly incomparably simpler
than writing a paper.
1. M. Chizhov and D. Kirilova: Lepton assymetry effect on neutrino oscillations and primordial He-4 ;
astro-ph/0101083 (2001) .
2. D. Kirilova and M. Chizhov: Neutrino oscillations in the early universe;
For those of you who are
perhaps not used to electronic preprints,the numbers given above reffer
to the preprint archives in the Los Alamos National Laboratory. The general
url is http://xxx. lanl. gov/ .
3. M. Stavinschi and J. P. Zahn are co-editors of a
book "Advances in Solarresearch at Eclipses from
Ground and from Space".The editors do not have complete
bibliographical data, but it has been published in the NATO ASI series.
Celebonovic and W. Däppen : "The plasma-solid transition" ; preprint astro-ph/0102284
and submitted for publication.
5.The next issue of the
Serb. Astron. J. ,published by the Astronomical Observatory in Beograd is
currently being prepared; according to current plans, it willgo topress sometime
between May and September.
G. Giuricin,S. Samurovicet al. : "The
redshift-space two pointcorrelation
functions of galaxies and groups in the Nearby Optical Galaxy sample",preprint
last issue of ILBA contained a longer list of references. It seems to the
editors that a "big step forward" in this issue is the proposal
for solar physics work.
Projects like this were one of
the motives with which ILBA was proposed and launched in Belogradchik. We
can only hope that the number of such proposals will continue togrow, and of course that you will continue to inform us about your
results, ideas and problems, so that we can continue with ILBA.
Clear skies and speedy
computers to all,
