The zeroth issue of our nesletter has "gone out" some time ago. We admit that the reactions have not been as numerous as we had hoped,but the point is that they were all positive.Please,do not be "lazy" - the invitation is open and will remain so for all of you to tell us your opinions and proposals. Finally,the whole idea of ILBA is to make something useful, accessible to all of us and short.We hope that the material which we managed to accumulate in this issue will be sufficiently interesting so as to motivate you to react and send us your comments but also accounts of your results and plans.
the web siteFirst,some practical news. A wish was expressed during the meeting in Belogradchik that,apart from an electronic information letter on Balkan astronomy, a web page on the same subject should be set up.Well,it has been done.Issues od ILBA are now on the web,in Canada,at the address http://www.atm.dal.ca/~andromed/balk.html. They will be posted there probably until next spring or summer,so we should all be thinking about finding a new host.This web site belongs to my friend,Mr.Michael Boschat who is a very active amateur astronomer.His speciality is hunting of sun-grazing comets on photos taken by the SOHO satellite.As far as I know,he has so far discovered 22 of them!
Another practical information concerns the recent passages of the Leonid and Geminid meteor streams.The Leonids passed on November 17,and organized observation was attempted at two locations near the city of Valjevo in Serbia. In all, about 50 observers with differing experience took part. A quantitative result is that the ZHR (Zenithal Hourly Rate) was 260+/-40 on November 17 at 4:30 UT.Those of you who are interested in detail can contact Mr. Nikola Bozic, at bozicn@Tesla.rcub.bg.ac.yu.Another contact is Mr. Branislav Savic at firstname.lastname@example.org. The Geminids passed on December 12-16.Again,observation was performed near the city of Valjevo.The sky was variable and the estimated ZHR was: around 45 on the night of 12-13 December
around 110 on the night of 13-14 December.One of the observers saw 76 meteors in 5 hours of effective observation, and the maximal apparent magnitude was - 5. The contact addresses are the same as for the Leonids.
According to avaliable information, two meetings are being planned, in Romania and in Greece.
The meeting in Romania has a provisional title "The Sun
viewed from the South-Eastern
For details,contact Dr. Georgeta Maris (email@example.com) or Dr. Magda Stavinschi (firstname.lastname@example.org) at the Astronomical Institute of the Romanian Academy. A fax number for contact is +401 337 33 89 .
meeting for which we have information will be the 5th Hellenic
The main idea of ILBA is that we stay mutually informed about our ongoing work as well as about the plans for future research activities. In the following you will find a list of selected references to some papers published by astronomers and physicists from the Balkan countries. We deliberately say "some" because this list is certainly not the complete output of our countries in astronomy and related physics, but it was compiled from the data which you have sent. So, please, react, send us your results, and we shall through ILBA diffuse them further. In the following you will find a list of references to papers by authors from the Balkan countries:
1. M. M. Cirkovic and S. Samurovic:
Column Density Distribution of Galactic Ly alpha
A few words are in order about the plans of some of us for the future.
Dr. Daniela Kirilova from the Institute of Astronomy of the Bulgarian Academy of Sciences in Sofia is working on "Nonequilibrium porcesses in the early Universe". She is open to proposals for collaboration by anyone interested. The logical prerequisites are knowledge of theoretical physics and astrophysics. The e-mail of Dr.Kirilova is: email@example.com.
Dr. Luka C. Popovic from the Astronomical Observatory in Belgrade and collaborators are working in two domains: active galaxies and Stark broadening of spectral lines. Both of these are wide, so there is ample room for contacts and collaborations. If you are interested, contact Dr.Popovic at firstname.lastname@example.org
Milan M. Cirkovic has
three projects for the future:
THE FINAL NOTE
This is certainly the last issue of ILBA in this century and millenium.The editors hope that your interest in it will continue to grow,and that it will help us in the Balkans to stay in contact,and to show to those outside what is going on here in the domain of space research.
Merry Christmass and Happy New Year to all,
Dr.Milcho Tsvetkov Vladan Celebonovic
