International Conference
Tatranska Lomnica, Slovakia, August 17-21, 1998

Dear colleagues,
We are sending you the third and final announcement of the conference METEOROIDS 1998 being held at Tatranska Lomnica and organized by the Astronomical Institute, Slovak Academy of Sciences together with IAU Commission 22. Here you will find information on how to reach the conference site and other useful details relating to the event.
As noted in the second announcement, the conference will be held in the Conference Hall of the Hotel ACADEMIA next to the Astronomical Institute SAV at Stara Lesna (SAV - Slovak Academy of Sciences), which is about 1.5 km from the Tatranska Lomnica village and about 20 km from the district capital Poprad. Stara Lesna and Tatranska Lomnica are located at the foot of the Lomnicky Peak massive in the eastern part of the High Tatras Mountains. Poprad is in the northern part of Slovakia about 350 km from Bratislava.

(*) change in Studeny Potok Station

Bus: Bratislava (Bus Station) - Tatranska Lomnica

Bratislava (Bus Station) - Poprad
IC trains are the most comfortable. The present fare Bratislava-Poprad (344 km) for IC train is 313.- Sk (Slovak Crowns) - 1st class, 232.- Sk - 2nd class and for the other trains it is 267.- Sk and 178.- Sk, respectively. A seat reservation card is 10.- Sk. For the IC train this reservation is included in the price.
Money can be changed at the border crossing when you are travelling on the bus (it is a non-stop exchange office) and at Bratislava Railway Station, there is an exchange office (bank) operating each day at 7:30 - 18:00. Other banks are closed on Sundays.

*** The present exchange rate is 1 USD = 35 Sk (Slovak Crowns). ***

The best way to reach Bratislava Railway Station (in Slovak: "Hlavna stanica") from Bratislava Bus Station is to take a city trolly-bus No.210 (about 15 min. drive. Ticket per 8.- Sk has to be bought in advance either at a newspaper-stand or from slot-machines, which are located at tram or bus stops but require coins). Trolly-bus 210 is running on Saturdays and Sundays at about 15 minute intervals. On working days, the trolly-bus is No. 208 instead of 210. Alternatively, you can take a taxi just from the front of the Bus Station (price should be about 120-150.- Sk).
If you inform us in advance by e-mail about your arrival at Tatranska Lomnica or Poprad by a bus from Bratislava (the same Bus Station as you arrive from Vienna), we will meet you and drive you to the registration (Tatranska Lomnica to the hotel Academia is about 25 min. walk). The Poprad Bus Station is just next to the Poprad Railway Station.
We will also meet participants at the trains from Bratislava arriving at Poprad and drive them to the registration. The cars designated "Meteoroids 1998" will wait at the parking place beyond the Poprad railway station in the front of the hotel Europa and will leave Poprad at: 10:00, 14:00, 17:00 and 21:45 on Sunday (Aug.16) and at 10:00 and 14:00 on Monday (Aug.17).
Alternatively, you can take a taxi direct from the Poprad railway station. The distance from Poprad to the hotel Academia, where the registration will be held (by the shortest way) is 17 km and the price should be about 300-350.- Sk.
Participants coming by train from Ukraine arriving to Poprad at 22:16, please, inform us in advance.
The hotel Academia and the Astronomical Institute SAV are actually located in the area belonging to the village of Stara Lesna and are within walking distance from Tatranska Lomnica (15-20 min).
If you arrive by car, the shortest way to reach the hotel Academia is to drive from Poprad in the direction to Kezmarok and in the village of Velka Lomnica (after about 10 km drive) turn to left in the direction to Tatranska Lomnica. Then just beyond the village of Velka Lomnica turn to left to the village of Stara Lesna (about 4 km) and the conference site is beyond Stara Lesna in a recreation area were are located more hotels. About 1.5 km beyond Stara Lesna, on the right hand side you will see the hotel HORIZONT and just before the hotel turn to the right and on the end of the road (400 m) there is the hotel ACADEMIA and next to it is the Astronomical Institute SAV.

Registration and accommodation:

Registration will be at the hotel ACADEMIA and starts on Sunday noon (Aug.16) at 13:00 (see enclosed time schedule). Payment will only be accepted in Slovak Crowns but there will be an exchange office at the ACADEMIA operating during the registration period (Sunday: 13-20 on Monday: 08-12). REGISTRATION FEE is 150 USD for participants and 70 USD for accompanying persons and students. All who sent their registration forms and wished to stay at the hotel Academia have their accommodation reserved and the cost of ACCOMMODATION is as announced in the second announcement. For details see the second announcement. Those wishing to stay in pensions (prices are 5-8 USD per bed and night) will be driven to their pension after registration.
Note, the exchange office operating during the registration at ACADEMIA will not be equipped with facilities for using "cards" (Master, Visa etc.) or travel checks. The easiest way to pay is in cash; otherwise you have to go to the bankomat at Tatranska Lomnica (2 km). Information about using the cards is in the second announcemt. Cards cannot be used for bying train tickets or at local shops.

Scientific programme:

Also enclosed is the scientific programme of the conference. For the oral presentation (30 min. - review papers and 15 min. - contributed papers, included discussion) two overhead projectors and one slide projector will be available. Poster panels are 100x90 cm. Posters will be displayed for the whole period of the meeting and please, display your poster according to the number assigned to you.
According to the enclosed programme, there will be three poster sessions including a brief oral presentation of the results by the authors for 2 minutes in the lecture room (maximum 4 overheads) and just after the oral presentation of all posters of the session,there will be discussion in front of the posters. The poster presentations are scheduled for three afternoon sessions.
At the registration, each participant will receive the abstract book and final scientific programme. The proceedings of the conference will be published by the Astronomical Institute SAV.The SOC expects to receive the final versions of the papers by the end of September 1998. All the papers will undergo through a referee procedure.
Detail information how to prepare your papers for the Proceedings will be provided at the conference. The price of the Proceedings is included in the registration fee of participants.
