This is a preliminary announcement of the first PACIFIC NORTHWEST NUMBER THEORY CONFERENCE which will be held at Reed College, Portland, Oregon on Saturday, April 5. The following speakers will give one hour talks: David Boyd, University of British Columbia Ralph Greenberg, University of Washington Hendrik Lenstra, Jr., University of California, Berkeley Peter Stevenhagen, University of Amsterdam. This conference follows in the successful tradition of ``Pacific Northwest'' conferences in geometry and topology. This is the first Pacific Northwest number theory conference, and we hope that this will become an annual event. Talks will start at 10:30am and be finished by 5pm. Lunch and snacks will be provided. Registration will be $15 ($0 for students). No official arrangements will be made for dinner, or hotel/motel accommodations, or basketball tickets, or opera tickets ("Carmina Burana" and "I Pagliacci" are being performed by the Portland Opera Company Saturday evening), but the organizers will be happy to assist attendees who need help with arrangements for any of these. Please let one of the organizers of the conference know if you plan to attend, or if you want to be on the mailing list for the final announcement which will be mailed early in March.
