1998 CS1 Goldstone Radar Observations Planning


Background

(136849) 1998 CS1 was discovered by A. Nakamura at Kuma Kogen Observatory (Japan) on 
February 9, 1998.  It will approach within 0.0291 AU (11.3 lunar distances) on 
January 17, 2009.

Its absolute magnitude of 17.7 suggests a diameter within a factor of two of 0.9 km.
Spectroscopy obtained by M. D. Hicks and K. Lawrence at Palomar indicates that it's an Sq-type
object.  Lightcurves obtained by Joe Pollock (Appalachian State University) reveal
a 2.6-hour rotation period with an amplitude of about 0.2 magnitudes, suggestive 
of a shape with low-to-moderate elongation.  Subsequent lightcurves obtained by Michael
Hicks and Heath Rhoades at Table Mountain Observatory have revealed a consistent synodic
rotation period of 2.7 hours.

Goldstone observations are scheduled on January 13, 14, 17, 18, and 22.
Arecibo observations are scheduled on January 14-21.

This object will brighten to about 12th magnitude in mid-January and it will
be a good target for photometric and spectroscopic observations.

1998 CS1 has been classified as a "Potentially Hazardous Asteroid" by the 
Minor Planet Center.
