We find 87 reliable detections after filtering for the signal-to-noise ratio of the Yarkovsky drift esti- mate and making sure the estimate is compatible with the physical properties of the analyzed object. Furthermore, we find a list of 24 marginally significant detec- tions, for which future astrometry could result in a Yarkovsky detection. A further outcome of the filtering procedure is a list of detections that we consider spurious because unrealistic or not explicable with the Yarkovsky effect. Among the smallest asteroids of our sample, we determined four detections of solar radiation pressure, in addition to the Yarkovsky effect. As the data volume increases in the near fu- ture, our goal is to develop methods to generate very long lists of asteroids with reliably detected Yarkovsky effect, with limited amounts of case by case specific adjustments.

  • Arizona-Based Astronomers Characterize One of the Smallest Known Asteroids
    PRESS RELEASE FOR IMMEDIATE RELEASE: 30 November 2016 ***Contact details appear below*** Arizona-based Astronomers Characterize One of the Smallest Known Asteroids A team of astronomers have obtained observations of the smallest asteroid –with a diameter of only two meters (six feet)—ever characterized in detail. The asteroid, named 2015 TC25, is also one of the brightest near-Earth asteroids ever discovered, reflecting 60 percent of the sunlight that falls on it. Discovered by the University of Arizona’s Catalina Sky Survey last October, 2015 TC25 was studied extensively by a team led by Vishnu Reddy, an assistant professor at the University of Arizona's Lunar and Planetary Laboratory. Other participating institutions include Lowell Observatory and Northern Arizona University. The team used four Earth-based telescopes for the study, published this month in The Astronomical Journal. Reddy argues that new observations from the NASA Infrared Telescope Facility and Arecibo Planetary Radar show that 2015 TC25's surface is similar to a rare type of highly reflective meteorite called aubrites. Aubrites consist of very bright minerals, mostly silicates, that formed in an oxygen-free, basaltic environment at very high temperatures. Only one out of every 1,000 meteorites that fall to Earth belong to this class. "This is the first time we have optical, infrared, and radar data on such a small asteroid, which is essentially a meteoroid," said Reddy. "You can think of it as a meteorite floating in space that hasn't hit the atmosphere and made it to the ground—yet." “2015 TC25 is one of the five smallest Near-Earth Objects ever observed to measure rotation rate” says Audrey Thirouin from Lowell Observatory.

Northcott and assembled for publication by Helen Sawyer Hogg. It included all articles published in the Journal during the interval 1932–1966, Volumes 26–60. In the intervening years the Journal has undergone a variety of changes. In 1970 the National Newsletter was published along with the Journal, being bound with the regular pages of the Journal. In 1978 the National Newsletter was physically separated but still included with the Journal, and in 1989 it became simply the Newsletter/Bulletin and in 1991 the Bulletin. That continued until the eventual merger of the two publications into the new Journal in 1997.
