Lodging & Travel

  • Lodging information can be found on the DDA web site at the URL

         http://dda.harvard.edu/meetings/yosemite2000/res.html

  • Lodging deadline: We have reserved a block of rooms at the Yosemite Lodge, but that block goes away after March 9. To get a room in the DDA block, you must make reservations by then. For reservations information, please see the DDA Yosemite room reservations page. Of specific note: you MUST use the registration form supplied by the Yosemite Concession Services and available on the DDA Yosemite room reservations page. Room reservation forms can be either mailed or FAXed to Yosemite Concession Services.

  • Here is some lodging advice from our Local Host:
    It occurs to me to suggest that you add a note to the Newsletter encouraging attendees to share rooms with others. Our room block is not all that large, the rooms are pricey (the flood is the culprit here), and the attractions of Yosemite are its great outdoors (NOT the four walls of your room).

  • Here is some travel advice from our Local Host:
    Airports of choice include SF and Fresno. Bakersfield is worth mentioning, even though Fresno is closer to the Park. Of course, Los Angeles is always in the equation, particularly for members linking up with our southern California attendees for the final carpool to the Park.

    There are four entrances to the Park; three from the West and one from the East (via Lee Vining). The entrance from the East will be closed due to snow at the time of our meeting. The western entrances each have their advantages. The northernmost entrance (via Rte. 120) is best for attendees arriving via San Francisco or other points north. The southernmost entrance (via Rte. 41) is similarly best for attendees such as myself arriving from points in southern California. The central entrance (via Rte. 140) provides access through El Portal, where the Cedar Lodge is located. Cedar Lodge provides comfortable accommodations closest to but outside of the Park. For our attendees slow to make room reservations, Cedar Lodge may be the best option after our room block fills up.

    A map, of moderate adequacy, is available of the Yosemite environs at the Yosemite.com link on our website. In all honesty, if you are unfamiliar with the necessary details of the roads in California, I think you should be advised to get a detailed road map of the state from your travel agent.

    Abstracts

    Electronic Voting is On the Horizon

    The DDA is moving towards allowing members to cast their ballots via electronic means (email, web, FAX), in addition to the traditional snail mail. As with all things formal, the process takes time. Currently, the DDA Committee is hashing out the exact wording of the proposed changes. In accordance with the DDA bylaws, these changes will be submitted to the AAS Council at the next Council meeting in July. After that, the changes (as well as pertinent comments from the AAS Council and the DDA Committee) will be distributed to the DDA membership. The amendments will then be discussed at the 2001 DDA Business meeting, followed by formal ballots sent to the entire membership. Assuming the amendments pass, then the electronic voting options will be available for the 2002 DDA elections.

    New High Precision Ephemerides Available for Fifteen of the Largest Asteroids

    [From James Hilton, USNO]

    The U.S. Naval Observatory is making available a CD-ROM version of USNO/AE98, the high precision ephemerides of fifteen of the largest asteroids. These are the asteroid ephemerides which will appear in the Astronomical Almanac beginning with the edition for the year 2000. USNO/AE98 includes the asteroids 1 Ceres, 2 Pallas, 3 Juno, 4 Vesta, 6 Hebe, 7 Iris, 8 Flora, 9 Metis, 10 Hygiea, 15 Eunomia, 16 Psyche, 52 Europa, 65 Cybele, 511 Davida, and 704 Interamnia. USNO/AE98 is based on the JPL DE405 planetary ephemerides and covers the period 1799 November 16 (JD 2378450.5) through 2100 February 1 (JD 2488100.5). The CD-ROM also includes software to compress the ephemerides and interpolate the ephemerides for any arbitrary date within the range of USNO/AE98.

    The CD-ROM is ISO 9660 compliant and will work on all systems with ISO 9660 compliant CD-ROM drives.

    For more information on USNO/AE98, including the new mass determinations for Ceres, Pallas, and Vesta, see Hilton, J.L. 1999, 'U.S. Naval Observatory Ephemerides of the Largest Asteroids,' Astronomical Journal, 117, pp. 1077-1086. (Click here for ADS Abstract.) For a copy of the CD-ROM contact either James Hilton or The Astronomical Applications Department, U.S. Naval Observatory, 3450 Massachusetts Ave. NW, Washington, DC 20392, or send an email to jhilton@aa.usno.navy.mil.

    Detailed Electronic Abstract Submission Instructions

    The AAS is again handling abstracts for our DDA meeting. The AAS web page to do this has not been set up yet, so the information below is only a highly-likely guess, based on last year's instructions. When the AAS page is ready (the first week of February), I'll immediately send out a notice with further instruction via email. You cannot submit an abstract until the AAS form is ready after the first of February.
    Electronic Submission via the World Wide Web
    You can submit your abstract electronically just as for an AAS meeting anytime before March 2, 2000. There is a World Wide Web submission form available at the following URL:

    http://www.aas.org/~abstract/abstracts.html

    When you go to the above link, press the "I want to use the Web form" button, then select "DDA 2000", fill in the number of authors and number of collaborations, and press the "Create an abstract form for me!" button.

    If you have any questions about electronic submission while you are preparing your abstract, please contact the AAS Executive Office for assistance. You can call the office at 202-328-2010, or send email to abs-help@aas.org.

    Electronic Acknowledgment of Abstract Receipt
    Two acknowledgments are sent. The first is a copy of the submission sent within minutes to the submitter's browser. The second is sent to the first/presenting author's email address, it confirms acceptance and includes a running identification number.

    If you do not receive these confirmations, DO NOT RESUBMIT THE ABSTRACT. Please contact the Executive Office by calling 202-328-2010 or by sending email to abs-help@aas.org.

    Corrections to your Abstract
    If you notice an error in your abstract after submission, send details of the correction to abs-help@aas.org and the correction will be made for you. We cannot guarantee that corrections received after the abstract deadline will be processed.
    NOTE: If you do not have access to the Web, the AAS Executive Office will make arrangements to include your abstract. Please contact them for assistance, 202-328-2010, or send email to abs-help@aas.org.
