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 Science on 10 June '07
- "Acfer 094 presolar silicates characterized using NanoSIMS and Auger Nanoprobe" by Bose, M. with C. Floss & F.J. Stadermann, abstract & PDF from Frank J. Stadermann 18 May - Quote: "Here we report further searches for presolar silicate and oxide grains in Acfer 094."
- "Presolar Fe oxide from the Acfer 094 carbonaceous chondrite" by Stadermann, F.J. with M. Bose & C. Floss, abstract & PDF from Frank J. Stadermann 18 May - Quote: "We have identified presolar grains from Acfer 094 on the basis of their O isotopic compositions and determined their elemental compositions. Here we discuss a unique grain, 34C-10, that consists essentially only of Fe and O."
- "Auger analysis of presolar silicates in Acfer 094 & the discovery of a presolar CAI" by Vollmer, C. with F.J. Stadermann, M. Bose & 3 others, abstract & PDF from Frank J. Stadermann 18 May - Quote: "Mineralogical characterization of presolar silicates is an analytical challenge due to their small size (usually <0.5 um) and surrounding 'normal' silicates... Transmission electron microscopy (TEM) is typically the method of choice, but preparation ... is a difficult and time consuming task. Auger spectroscopy provides a promising analytical alternative: elemental information ... can be obtained with ~10-20 nm resolution without elaborate sample preparation."
NEOCP Activity on 10 June '07
The MPC's NEO Confirmation Page has 7 listings: 1 new, 6 updated
When last checked this day, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had one new and six updated listings. Of these, one was a "one nighter."
