Chronology

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 25 May '07

"Did a One-Two Punch Form the Solar System?" Sky & Telescope 24 May - Quote: "Having our solar system come together in a crowded stellar neighborhood might also explain why a growing number of objects in the distant Kuiper Belt, such as 90377 Sedna, have swollen, highly elongated orbits that can't be explained by planetary interactions long ago."
"Asteroid discovered by UNT grad student," Pegasus News 25 May - Quote: "Instead of frittering away his non-study time [physics grad David McNeil] concentrates on pictures taken by telescopes connected with the International Asteroid Search Campaign, an internet-based initiative employing eager (and free) student laborers in a quest to find as-yet-uncharted space rocks."
"Quebec crater is out of this world," Toronto Globe & Mail 25 May - Quote: "Pingualuit Crater near the Hudson Strait [is] one of the deepest lakes in North America... [Scientists extracted from its bottom] a nine-metre sediment core ... that researchers hope will yield clues about climate change dating to the last interglacial period 120,000 years ago."
Small asteroids: (updated) Yesterday came the discovery announcement of small asteroid 2007 KE4, which both JPL and NEODyS have now posted as an impact risk (see below). It was discovered yesterday morning by the Catalina Sky Survey (CSS) in Arizona and will pass Earth two days from now at about 7.0 lunar distances. In today's news (below) there is the discovery of another small asteroid, 2007 KO4, found from Arizona three days ago by the Mt. Lemmon Survey, which alone confirmed it this morning. Although calculations show that 2007 KO4 can come close to Earth, and in fact JPL has now posted it as an impact risk (see below), there is no close approach this time around.
Today's DOU MPEC (below) reports that Spacewatch in Arizona used its 1.8-meter telescope to recover 2004 LK on its second opposition. And Antares Observatory in Illinois added about 30 days to the eight-day observing arc for 2007 GU4, which was calculated to go out of view for most NEO observers around May 12th, and which Antares reported on May 22nd at visual magnitude V=22.7-9. Also today, 2007 KV2 was delisted as an impact risk.

NEOCP Activity on 25 May '07

The MPC's NEO Confirmation Page has 6 listings: 2 new, 4 updated

When last checked at 2355 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had two new and four updated listings. Of these, four were "one nighters." Major News counted a total of ten objects listed on the NEOCP at some point on this day.

Impact Risk Monitoring on 25 May '07

**Summary Risk Table for Risk Assessments Updated Today** (last checks: NEODyS and JPL at 2356 UTC)
Note that the time horizon for JPL is 100 years from today and for NEODyS is usually the year 2080.
For the latest official risk assessments, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) risk pages.

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale

For a list of all risk-rated objects recently in view, see our ephemerides page.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from an orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" for more about all this.
