Updates from Past Recipients of the Shoemaker NEO Grants

Bruce Betts • August 17, 2005

Update as of July 28, 2005 Following last year's Potentially Hazardous Asteroid and a few other non-main-belt discoveries, I looked into what improvements I could make to more efficiently image the sky. The major advance involved the design of a 3-lens corrector comprising 2 stock lenses and a custom lens I made myself.

Astronomers Revise Torino Scale Asteroid Advisory System

A.J.S. Rayl • April 20, 2005

Astronomers have revised the Torino scale, the color-coded advisory system to assess the threat of asteroids and other near-Earth objects (NEOs) to make it easier for the public to understand.

Close Your Left Eye, Then Your Right: Simultaneous Observations of Asteroid 4179 Toutatis from Two Chilean Telescopes Demonstrate Parallax

Emily Lakdawalla • September 29, 2004

This morning, asteroid 4179 Toutatis was so close to Earth that simultaneous observations from two telescopes in the same country could show parallax that is obvious even to the least experienced observer. The two telescopes belong to The European Southern Observatory and are located at La Silla and Paranal in Chile

Very Close Approach by Asteroid 4179 Toutatis: It's Not a Crisis, It's an Opportunity

Emily Lakdawalla • September 27, 2004

On Wednesday, September 29, Earth will dodge a cannonball: the Near-Earth Asteroid known as 4179 Toutatis will buzz by at a distance only four times the distance from the Earth to the Moon -- about one and a half million kilometers, or about a million miles. But, as the wisdom goes, "close" only counts in horseshoes and hand grenades; Toutatis' flyby will have no effect whatsoever on us.

Updates from Past Recipients of the Shoemaker NEO Grants

Bruce Betts • April 16, 2004

Update as of March 24, 2004 2003 was a good year with 50,779 asteroid astrometric observations submitted, including known NEOs and the discovery of a new Aten-class object, 2003 UY12. Based upon the volume of astrometric observations submitted, observatory code 683 was the world's eighth most productive asteroid astrometry station.

Updates from Past Recipients of the Shoemaker NEO Grants

Bruce Betts • March 20, 2001

Update as of March 20, 2001 I just wanted to express my appreciation again to The Planetary Society for the Shoemaker Grant. Apogee Instruments delivered the AP6Ep purchased with the grant on 9 March 2001. Critical mass on all of the other components associated with implementing the proposal was reached last week.
