Minor-Object News on 18 August '07

"The meteor hunter," Sacramento Bee 18 Aug. - Quote: "Robert Lunsford, operations manager of the American Meteor Society, who keeps the society's fireball log [said] 'This is one of the top 10 events I've had since I began recording back in 2005'... Just after midnight on Aug. 11, it was seen from Fair Oaks to San Francisco to Gilroy, and filmed by a Yuba City sky watcher, but the fireball made its most dramatic appearance above Tuolumne County." - Note: The article title refers to meteorite hunter/collector Robert Ward, and the article includes links to Larry Stange's all-sky camera video and a map showing observer locations. See also a copy of the same article with different photos at the Modesto Bee today, "Look! Up in the sky! Search for meteorites leads to Lode," as well as A/CC's Tuesday report with more news links and the AMS fireball log (event "274" is assigned to all possibly related reports, but some appear to be from separate events). {permalink}
"Nerds? Yes. Also rock stars," Toronto Star 18 Aug. - Quote: "But while the majority of meteorites available to collectors in the past 15 years have come from the Sahara, [Patrick] Herrmann prefers hunting closer to home. Armed with metal detector, shovel and $2-per-acre lease, he's unearthed many a rusty tool during three expeditions to the United States -- but also, several prized meteorites." {permalink}
- "Where to go in search of meteorites," Toronto Star 18 Aug. - Quote: "No one can remove meteorites from federal land in the United States, whereas it's finders keepers if found on Crown land -- but only if you're Canadian. Hunters hoping to hawk their wares overseas must first offer the goods to a research institution under federal cultural and heritage laws." {permalink}
"NASA STS-118 Execute Package FD11," NASA JSC at SpaceRef.com 18 Aug. - Quote: "[No] definitive correlations were found between the Perseids and the increased indications since half of the indications occurred during Earth blockage. Only a single indication occurred during the Perseids peak with both wings being continuously monitored." - Note: This is part of a discussion about why "compared to previous flights" there has been a "50% increase in the number of indications" from the Space Shuttle Endeavor's wing leading edge impact sensors. Endeavor has also taken an Astronaut-witnessed impact to one of its windows while currently in space. "MMOD" is an acronym for "micrometeoroid/orbital debris." {permalink}
"Six from MIT win Fulbright student travel grants," MIT 17 Aug. - Quote: "Francesca DeMeo ... will travel to France to study at the Paris Observatory. While there, she will begin to characterize asteroids with a special emphasis on potentially hazardous objects [to] complete her Ph.D. work in planetary science." {permalink}

Impact Risk Monitoring on 18 August '07

**Summary Risk Table for Risk Assessments Updated Today** (last checks: NEODyS and JPL at 2354 UTC)
See the CRT page for a list of all objects rated recently as risks.
Note that the time horizon for JPL is 100 years from today and for NEODyS is now usually the year 2090.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) risk pages.

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 this.
