4. AAS LEAP SECOND COMMITTEE
Working Party-7A of the International Telecommunications Union Radiocommunications Section (ITU-R) presently is considering a draft recommendation to increase the maximum time difference between UT1 (based on Earth rotation) and UTC (Coordinated Universal Time) from less than a second to as much as an hour.
This would effectively eliminate the leap second that presently is put into effect every year or two. Depending on the application (or lack thereof) of the UT1-UTC difference (for instance, in telescope pointing programs), this proposal might have significant operational and financial impact on the American astronomical community. Therefore, the American Astronomical Society has formed an ad-hoc committee to consider this proposal, and make a recommendation to the AAS Council at its meeting in January 2007. This recommendation, in turn, potentially provides the basis for a recommendation from the AAS to the U.S. State Department, and hence to the ITU at its meeting in 2007.
Members of the AAS Leap Second Committee are Todd Boroson (NOAO), Suzanne Hawley (University of Washington), Dennis McCarthy (USNO), Bill Owen (JPL), Kenneth Seidelmann (University of Virginia, and Jim Ulvestad (NRAO, chair).
This committee solicits input on the leapsecond issue from professional and amateur astronomers, in order to develop its recommendation to the AAS Council. We request that all input be submitted to the American Astronomical Society, by e-mail to email@example.com, no later than September 15, 2006.
In November 2005, the AAS Division of Dynamical Astronomy (DDA) produced a report to the AAS Council on this topic, entitled "Coordinated Universal Time (UTC) and the Status of the Leap Second." Readers who are interested in the subject may access the entire report through the AAS web site at http://www.aas.org/policy/LeapSecondCommittee.html .
5. SLOAN DIGITAL SKY SURVEY (SDSS)
On June 28, the Sloan Digital Sky Survey (SDSS) made publicly available its Fifth Data Release (DR5). The DR5 includes deep and uniformly calibrated photometric data in five bands (ugriz) of 215 million objects over 8000 square degrees of sky, as well as optical spectroscopy of over 1,050,000 objects. The data and a full description of their attributes may be found on the web by following the "Data Release Five" link from http://www.sdss.org or by going directly to http://www.sdss.org/dr5 or to the catalog database at http://cas.sdss.org/astro.
6. POLLOCK AWARD PROPOSALS DUE
Deadline: 28 October 2006
Dudley Observatory invites applications for the Pollock Award, a grant of up to $5,000 for a project on the history of astronomy. The deadline for receipt of proposals is 28 October, 2006. See http://www.dudleyobservatory.org/pollock_award.htm for eligibility and proposal requirements.
The purpose of the Award is to provide encouragement and support for an innovative project in the history of astronomy or astrophysics, to be undertaken by a faculty member, research associate, or postdoctoral associated with a college, university, nonprofit research institution or observatory located in North America. Applications from persons meeting the other requirements, who are not currently affiliated with any institution will also be considered.
An American Astronomical Society (AAS) Electronic Announcement is mailed to all members around the 10th of each month. Included are important items that do not fit into the schedule of the AAS Newsletter. Because of volume, Meeting Announcements are generally not included.
Items for possible inclusion in this Announcement series should be sent to mailto:firstname.lastname@example.org. Keep announcement short and refer readers to sources of additional information.
