(7888) 1993 UC Goldstone Radar Observations Planning


Background


(7888) 1993 UC was discovered at Siding Spring Observatory, Australia, on October 20, 1993. 
This asteroid will approach within 0.126 AU (49 lunar distances) on March 20, 2013.
Observations are scheduled at Goldstone from March 18-22 and at Arecibo from March 12-17.
This object is not observable at Arecibo on the date of closest approach because it will be
too far north.  Consequently, all the Goldstone observations will occur on dates when Arecibo
cannot track this asteroid.

1993 UC is a relatively large asteroid with a diameter of about 2.7 km and an optical albedo
of about 0.2.  It has a rapid rotation period of 2.34 hours and a low lightcurve amplitude of
0.1 magnitudes that suggests a shape with a low elongation.
Pravec et al. (2006) estimated that about 2/3 of near-Earth
asteroids with such rapid rotation periods have satellites, so we may see a companion.

The orbit of this asteroid has an unusually high inclination (i = 26 deg) and a large eccentricity (e = 0.66).     
It has a Tisserand parameter of 3.055 that is close to the classical boundary between objects with
asteroidal and cometary orbits.

1993 UC will probably be a relatively weak target at Goldstone and we expect to devote most of
our time to CW observations, although it's possible that we may obtain coarse-resolution ranging
data.   Due the large size and rapid rotation, we're expecting a bandwidth of about 120 Hz; 
furthermore, short integrations of only about 1 run (~300 seconds) will be required to avoid
rotational smear.

The SNRs will be much stronger at Arecibo and we hope to obtain image with 1 us (150 m) resolution, which 
should allow us to resolve the shape and search for satellites. 

1993 UC is currently very close to the Sun and it will not be a good optical target until the end of March
after radar observations conclude.  This is the closest encounter by 1993 UC until 2055.

Using 410 optical measurements (1989-Oct-28 to 2012-Nov-25),
7888 (1993 UC) orbit solution #44 was estimated. OSOD and nominal
predicts were established on rserv in the /a7888 sub-directory.

Setups


Due to its large diameter and rapid rotation period, we are expecting a bandwidth of about 120 Hz.

We're going to start with the following setup with the hope of seeing an echo quickly, and
then we'll probably increase the length of the FFT in order to estimate the bandwdith.

CW setup:
---------------------------------------------------------------------------
TX polarization           RCP
RCV polarization          LCP & RCP
Frequency hops:           4
Dwell:                    30 seconds
Bandwidth:                8000 Hz 
Sampling interval:        1250 x 0.1 usec
FFT for PFS files:        512 for 15.6 Hz resolution 

Ranging setups:
---------------------------------------------------------------------------
10-usec
baud             10 usec
code            127
PRP            1270 usec
FFT             128   
ncoh              1 
bandwidth       787 Hz   
resolution      12.3 Hz
TXOFF          +100Hz  (echo in bin 32+8=40)
---------------------------------------------------------------------------
11-usec 
baud             11 usec
code            127
PRP            1397 usec
FFT              64  
ncoh              1 
bandwidth       716 Hz

TXOFF          +100 Hz  (echo in bin 32+9=41)
