2002 VE68 Planning

Background 

2002 VE68 was discovered by the Lowell Observatory Near-Earth Object
Search (LONEOS) on November 11.  At the time of its discovery,
the asteroid was about 0.035 AU from Earth (about 13 lunar distances)
and already receding.  Its absolute magnitude of 20.1 suggests that it
is within a factor of two of about 300 meters in diameter.  Due to its 
size and the proximity of its orbit to that of Earth, 2002 VE68 has been 
classified as a "Potentially  Hazardous Asteroid" by the International 
Astronomical Union's Minor Planet Center.

A very preliminary lightcurve obtained by Lenka Sarounova at Ondrejov 
Observatory (Czech Republic) suggests that this object is an elongated,
slow rotator with a period of roughly 12 hours.

2002 VE68 is a strong target at Goldstone and Arecibo early this week, 
but it cannot be observed at Arecibo because that telescope is configured for
other observations.  Consequently, Goldstone provides the only
opportunity to image this asteroid and utilize radar to improve its
orbit until the next close approach in 2010.  

Goldstone observations are scheduled for November 14 and 15 and are possible 
due to the generosity of the Voyager 1 team and and Dr. Michael Klein, who 
relinquished telescope time to us.

Orbital and Physical Characteristics
 orbit type               Aten      
 semimajor axis           0.724 AU     
 eccentricity             0.409        
 inclination              8.94°       
 perihelion distance      0.428 AU     
 aphelion distance        1.021 AU     
 absolute magnitude (H)  20.1
 diameter                 0.15 to 0.6 km  
 rotation period          ~12 hours ?
 lightcurve amplitude     ~0.9 mag  ?   
 spectral class           unknown      

The Doppler uncertainty for the second track is small, so we 
will start with CW by sampling at 4 kHz with a 16384-FFT in order to resolve the echo.
Once we have a detection, we'll go to coarse-resolution ranging and then decide what to 
do next depending on the SNR.

There is a new orbit solution in Horizons. 31 new observations
(but still from the same day) lengthen the arc only 0.2 days:

  With 101 optical observations spanning Nov 11-12, 2002 VE68
solution #7 was computed, having the 3-sigma X-band uncertainties 
shown below.

17-NOV-2002 00:00     16.018    1431.312    0.199856

  With such a short arc, the possibility of a systematic
bias not reflected in the above statistical uncertainties 
is possible, but there is no evidence of it now.

------------------------------------------------------

2002 Nov 14

   No new optical data has been reported, so solution #9
remains the current best. Addition of the Doppler, with the
existing 101 optical observations results in 3-sigma X-band 
uncertainties of:

  For solution #11 (2 Doppler, 101 opt obs):

                      (")         Hz         (sec)

  The 2nd Doppler, at +/- 0.4 Hz dominates the solution
with a residual of ~ 0.

------------------------------------------------------

2002 Nov 14

   Including John Rogers' 5 e-mailed optical measurements,
solution #14 has these uncertainties:

      DATE          Pointing  X-band Dop     Delay  
                      (")         Hz         (sec)

17-NOV-2002 00:00      5.925      22.922    0.009824

   Files have been updated on Stealth.

   Comparing the new optical data to solution #11,
solution #11 predicts were 2 and 3 arcsec off the
actual measurements.

   Fitting the new optical data revealed an outlier 
measurement earlier in the data set that had previously 
been fit.  Now it is excluded from the solution.
