June 5, 1998 Dear Participant, Please find below updated information about the BLACK HOLE Workshop in Gr\"aft{\aa}vallen, Sweden (June 29 - July 4, 1998). The detailed program is appended below. You can also find it at http://www.astro.su.se/groups/head/bh98_program.html We still do not have the information from all the participants about your arrival/departure times (see below). We would appreciate receiving this before June 20. If not, you may have to arrange your own transportation from \"Ostersund to Gr\"aft{\aa}vallen. Those of you who asked us to book airtickets from Stockholm to \"Ostersund and back should have received confirmation from us. Those of you who asked us to book a hotel in Saltsj\"obaden, please, check below whether the dates are correct. Hotel "V{\aa}r G{\aa}rd" (red houses on the left side of the railroad) is located just 100m from Saltsj\"obaden train station. See Stockholm Observatory home page http://www.astro.su.se/ on how to get to Saltsj\"obaden. Finally, we would like the 40 min speakers to pay attention to the fact there are 15 graduate students attending the conference (not all of them are working in the field). We would therefore like to ask these speakers to begin their talks with a general introduction that would be understandable to a wider audience. Looking forward to seeing you in Sweden, Best regards, Juri Poutanen, Roland Svensson (on behalf of the organizing committee) ************************************************************************** HIGH ENERGY PROCESSES IN ACCRETING BLACK HOLES: OBSERVATIONAL AND THEORETICAL ADVANCES DUE TO ONGOING SPACE MISSIONS ************************************************************************* June 29 - July 4, 1998 ************************************************************************** Sponsored by Anna-Greeta and Holger Crafoords Fund NFR (Swedish Natural Science Research Council) NORDITA (Nordic Institute for Theoretical Physics, Copenhagen) NorFA (Nordic Academy for Advanced Studies) TAC (Theoretical Astrophysics Center, Copenhagen) Wenner-Gren Center Foundation for Scientific Research ************************************************************************* Scientific Organizing Committee: Igor Novikov Juri Poutanen Roland Svensson Andrzej Zdziarski ************************************************************************** Local Organizing Committee: Juri Poutanen, Roland Svensson ************************************************************************** HOME PAGE http://www.astro.su.se/groups/head/BH98.html ************************************************************************** PROCEEDINGS will be published in the Astronomical Society of Pacific Conference Series.
