WELCOME to A/CC's prototype daily news publication designed to be the viewing end of a planned autonomous 24-hour news service. The new tools and this publication format are working well enough now to share with readers. It is expected that this approach will require less time to maintain than our previous news and small asteroid pages, which were retired on May 14th. There's still more development ahead and there probably will be some glitches along the way, but this is what's needed to keep up with the increasing pace of minor-object news. The CRT page will be maintained separately for a little while longer, until all of this is working smoothly. And the CRT and small-asteroid ephemerides will be kept going.
Minor-Object News on 4 June '07
- Book reports: Ed Grondine, whose name will be familiar to readers of the Cambridge Correspondence Network (CCNet), writes to advise that his book, "Man and Impact in the Americas, which is the first survey of the effects of comet and asteroid impacts on the first peoples in the Americas, is available through Amazon.com," where it sells for $34.95. It is also available from Crow Clan Jewelry for $25.00. (There may be shipping fees from either source.)
The Space Review posted a review today of Peter Bond's book, Distant Worlds, which is described as "a good review of our (more-or-less) current understanding of the solar system, particularly for those people not terribly familiar with anything more than the basics." See also the book publisher's April 26th news release at EurekAlert. In today's review, there is also mention of Peter A. Weintraub's, Is Pluto a Planet, billed as "a historical journey through the Solar System." See The Space Review's April 30th report for more about that book.
- "NASA to enter new Dawn in probing space's origins," Pasadena Star-News 4 June - Quote: "Once Dawn does reach space, it will begin its spiraling journey, looping around the sun in three ever-widening circles. The first circle will take it past Mars, the second to the asteroid Vesta and the third to Ceres."
- "Pad 17A crane to be fixed mid-week," Florida Today 4 June - Quote: "Preparations ... are expected to resume mid-week, when a broken crane is expected to be repaired... The crane broke Wednesday, and apparently will cause at least a week's delay in the scheduled June 30 launch."
Minor-Object Science on 4 June '07
- "Gemini Observations of Disks and Jets in Young Stellar Objects and in Active Galaxies" by McGregor, Peter with Michael Dopita, Ralph Sutherland & 2 others, abstract & PDF at arXiv.org 4 June - Quote: "In the T-Tauri stars HV Tau C and DG Tau we see highly-collimated bipolar outflows in the [Fe II] 1.644 micron line, surrounded by a slower molecular bipolar outflow seen in the H_2 lines."
NEOCP Activity on 4 June '07
The MPC's NEO Confirmation Page has 2 listings: 2 new
When last checked at 2358 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had two new listings. Both of these were "one nighters." This listing info is unchanged since when checked at 0106 UTC on today.
