2008 EV5 Goldstone Radar Observations Planning
Background
The 2008 EV5 Goldstone observations are dedicated to the memory of Steve Ostro,
who died early on the morning of December 15. He was a uniquely gifted man
of enormous energy, intensity, passion, insight, and intellect; a very warm person;
and a close friend. We will miss him enormously.
2008 EV5 was discovered by the Mt. Lemmon Survey on March 4, 2008.
It will approach within 0.0216 AU (8.4 lunar distances) on December 23 when it
will be a strong radar target at Goldstone.
The absolute magnitude of 20.0 suggests a diameter within a factor of two of 320 meters;
otherwise nothing is known about its physical properties.
Goldstone observations are scheduled on December 16-23.
Arecibo observations are scheduled on December 22-24 and 27.
This object will brighten to about 13th magnitude around Christmas and it will
be an excellent target for photometric and spectroscopic observations.
2008 EV5 has been classified as a "Potentially Hazardous Asteroid" by the
Minor Planet Center.
We want to thank Rob McNaught at Siding Spring Observatory (Australia) for
obtaining astrometry to support radar observations of this object.

From Jon Giorgini, 2008 December 17:
Including another night of optical from Rob (92 opt. measurements
2008-Mar-4 to 2008-Dec-16), and the one delay discussed from Dec 17,
2008 EV5 soln #31 was computed.
