                          SECOND  ANNOUNCEMENT


-------------------------------------------------------------------------

We would like to bring to your attention again the Cosmic Ray International
Seminar (CRIS 2004) "GZK and Surroundings",  which will be held in Catania
from May 31 through  June 4,  2004 and will be devoted to high energy cosmic
ray physics and related questions.

We invite you to visit or re-visit the CRIS 2004 Web site

http://www.ct.infn.it/~cris/

which has been updated with more detailed information about the logistic and
scientific aspects of the Conference. In particular,

     *** PRE-REGISTRATION AND ABSTRACT SUBMISSION IS NOW OPEN ***

You can conveniently pre-register and submit an abstract directly from your
Web browser.

A updated preliminary list of speakers is already available in the
Conference web page.


CRIS 2004 scientific topics:

The CRIS 2004 Conference will focus on ultra high energy cosmic rays close
to the GZK cutoff, predicted by K. Greisen and, independently, by
G.T.Zatsepin and V.A. Kuz'min in 1966.

The very fact of the detection of events with primary energy larger than the
GZK cutoff, the controversial discrepancy still existing between
experimental data, the wide spectrum of hypothesis about the origin of ultra
high energy cosmic rays and their nature poses a most fundamental problem
from a theoretical point of view. On the experimental side, a new generation
of experiments is being planned or is just completing installation and
starting to take data of unprecedented accuracy (for example, the Pierre
Auger Observatory).

This makes the present moment most timely as strong new data will soon play
a crucial role in the understanding of the problem of the nature, origin,
acceleration mechanism and anisotropy of ultra high energy cosmic rays. High
energy neutrino detection is also possible and it will be of greatest
importance.

The Conference venue will be the Hotel Nettuno
(http://www.hotel-nettuno.it)
a comfortable hotel in  down town Catania by the seaside.
We plan to host all participants in the Conference Hotel or in a couple of
less expensive Hotels.

CRIS 2004 is organized by the Catania Section of the Italian National
Institute of Nuclear Physics (INFN) and the University of Catania.

The International Advisory Committee is made of
