Speakers using LCD Projection must submit a ZIP disk or CD at least one day in advance of their talk. If you will not be at the Albuquerque Meeting the day before your talk, submit the disk to the AAS Office by 20 May 2002. (AAS Executive Office, Attn: Diana Alexander, 2000 Florida Ave., NW, Suite 400, Washington, DC 20009-1231)

Registrations are accepted in the AAS Office through 23 May 2002. If your registration will not be received by 23 May 2002, you should register on-site. There is no extra charge for registering on-site.

2. ARECIBO OBSERVING PROPOSALS
Deadline: 1 June 2002

NAIC invites proposals for use of the 305-m diameter Arecibo radio telescope for observing period 1 Oct 2002 - 31 May 2003.

Details of proposal submission, plus a web-based proposal cover sheet, are located at  http://www.naic.edu/~astro/proposals/index.html. A  guide for potential new users of the 305-m telescope can be found at http://www.naic.edu/~astro/guide/. Other user-related information is  available via http://www.naic.edu/aomenu.htm and http://www.naic.edu/~astro/astronomy.htm. Receivers for 327, 430 & 610 MHz, the whole range between 1.12 and 6.0 GHz (via a number of systems covering contiguous bands), and 8 - 10 GHz are now available. Pulsar, spectral-line, VLBI and continuum backends are available to exploit these. The latest information on receiver performance, plus backends and software availability, is to be found on the NAIC astronomy Web Pages.

Following recent resetting of the 305-m telescope surface, the telescope gain has now risen to essentially the design goals of the recent upgrade. This especially means significant improvements above 2 GHz, making of particular interest proposals for

using receivers at and above 2 GHz (gain ~ 7 K/Jy at 5 GHz, and up to 5 K/Jy at 8.5 GHz) for observing molecular lines. We note that this is the first opportunity to propose to Arecibo for the new 3-4 and 8-10 GHz receivers.

The Arecibo VLBA4 recorder for Very Long Baseline Interferometry (VLBI) is available for use with the VLBA, EVN and Global Network. Those wishing to include Arecibo in their VLBI observations should submit proposals directly to these networks as usual, rather
than to Arecibo, including special justification for the use of Arecibo.

3. NAIC CALL FOR USERS OF ARECIBO L-BAND ARRAY
Declaration of Interest by: 1 July 2002

The National Astronomy and Ionosphere Center's Arecibo L-band Feed Array (ALFA) will provide seven feeds, operating simultaneously at the focal plane of the Arecibo 305-m radio telescope. Each will be sensitive to frequencies between 1225MHz and 1525 MHz and provide two linear polarizations. Expected system temperatures are ~25K, with telescope gain ~10K/Jy for the central beam. The scientific potential of such an array is clearly illustrated by the great success of the Parkes Multi-Beam surveys for pulsars and HI.

Potential key scientific projects for ALFA include:

-Wide area pulsar surveys,
-Galactic HI surveys,
-Recombination Line surveys,
-Extragalactic HI surveys,
-Continuum surveys,
-SETI surveys.

This call is to identify individuals interested in preparing the scientific case for, and participating in, projects using ALFA.

NAIC will hold "consortia" workshops at Arecibo Observatory to encourage coordination among key projects, organization of smaller projects and promote the timely publication of results.

Please visit: http://alfa.naic.edu.

Workshops will start before the end of 2002, so don't delay. We hope to provide partial support for attending these meetings.

Paul Goldsmith, Director, NAIC (pfg@astro.cornell.edu)
Daniel Altschuler, Director, Arecibo Observatory (daniel@naic.edu)
Chris Salter, Head, Radio Astronomy Department (csalter@naic.edu)

The NAIC is operated by Cornell University under a cooperative agreement with the National Science Foundation.
