1999 RR28 Planning
Background
1999 RR28 was discovered by LINEAR on September 10, 1999; subsequently, precovery
observations dating back to 1987 have been identified
1999 RR28 will approach within 0.057 AU (22 lunar distances) on March 29. Its physical
properties are unknown but its absolute magnitude of 18.3 suggests a diameter within a
factor of two of 0.7 km.
Arecibo imaging on March 25 revealed a rounded object with a bandwidth of about 0.5 Hz
and a visible range extent of about 250 meters, suggesting a diameter of about 500 meters.
Due to its size and the proximity of its orbit to that of Earth, 1999 RR28 has been
classified as a "Potentially Hazardous Asteroid" by the International
Astronomical Union's Minor Planet Center.
These will be combined Goldstone and Arecibo observations.
Goldstone observations are scheduled on March 27, March 29, April 1, and April 2 and
Arecibo observations are scheduled on March 25, 26, 27, and April 2.

CW Setup
Arecibo imaging on March 25 revealed a bandwidth of about 0.5 Hz, so the bandwidth
at X-band should be about 1.8 Hz. Consequently, we'll use a CW setup that gives us
enough resolution to resolve the object in Doppler:
TX polarization RCP
RCV polarization LCP
Frequencies: 2
Dwell: 30 seconds
Bandwidth: 4000 Hz
Sampling interval: 2500 x 0.1 usec
