Dear Colleagues

The next trigger meeting will be on

Thursday, October 30, 1997, 1000h - 1800h at CERN *************************************************

Room and details of the agenda will be announced later.

We should have presentations of each of the subgroups, basically along the lines of the various notes being prepared. (My present knowledge of the status I copy below).

In addition we should have a discussion about how to proceed to arrive at a baseline option for the global trigger strategy.

Many greetings Ueli
