2004 XP14 Planning
Background
2004 XP14 was discovered by LINEAR on December 10, 2004. It will make a VERY close approach
within 0.00289 AU (only 1.1 lunar distances!) at 04:25 UT on July 3. Four hours and ten minutes
later, our first track starts at Goldstone when the asteroid is only 1.30 lunar distances from
Earth. Its physical properties are unknown, but its absolute magnitude of 19.3 suggests a diameter
within a factor of two of 430 meters. 2004 XP14 be the closest asteroid ever observed by radar, and
due to its estimated diameter, it will be the strongest asteroid ever targeted for radar observations.
Using past experience as a guide, there is a 1/6 chance that it is a binary.
Goldstone observations are scheduled on July 3, 4, and 6. The Goldstone SNRs will decrease
dramatically from the first to the third track as the asteroid rapidly recedes from Earth
(the round-trip times will increase by about a factor of ten between the start of the first
track and the end of the third, so the SNR will drop by a factor of about 10^4).
Due to the very short round-trip times, Goldstone observations on July 3 will be bistatic.
On July 4 we plan do so some monostatic ranging at the start of the track and then devote
the rest of the track to bistatic imaging. The round-trip time is much longer on July 6, so
observations on that date will be monostatic.
Radar observations are also scheduled at Evpatoria (Ukraine) on July 3 prior to and overlapping
the observations at Goldstone. The PI of the Evpatoria observations is Dimitrij Lupishko.
We will coordinate the observations on July 3 with our European colleagues by transmitting CW
at the start for them to receive at Evpatoria and at the 32 m Noto telescope in Italy and for us
to receive at DSS-13. The remainder of our time on July 3 will be for high-resolution
DSS14->DSS13 imaging.
Due to uncertainties in the asteroid's orbit, we are expecting at least one last-minute update
to the orbit within a day or two of the July 3 track.
Due to the proximity of its orbit to Earth and its diameter, 2004 XP14 has been classified as a
"Potentially Hazardous Asteroid" by the Minor Planet Center.
These observations have benefitted considerably from timely astrometry reported by
Rob McNaught at Siding Spring Observatory in Australia and Cristovao Jacques at CEAMIG-REA Observatory
in Brazil.

We have contacted several southern hemisphere observers who have graciously agreed to provide optical
astrometry shortly before the first Goldstone track.

From Jon Giorgini, 2006 June 28:
Now with 160 optical observations, 2004 XP14 solution #31 was computed.
Formal 3-sigma uncertainties are as shown below.
Solution #31 should have measurement systematic errors wrung out at this
point (there were some), and the statistics therefore more reliable/compatible
with the trajectory estimate.
You may have noticed recent Doppler solutions jumping outside 3-sigma between
orbit updates. Part of this is due to the measurement errors mentioned above
(perhaps compensated for now) but, for the next update, I will also move the
solution epoch to a date earlier than Jul 9 so as to reduce the effect of
having to linearly map residuals so far across an encounter having large
partial derivatives.

From Jon Giorgini, 2006 June 29:
With new optical data (163 measurements spanning 2004-Dec-10 to 2006-Jun-28)
and some further adjustments to data weights and estimator, 2004 XP14 solution
#33 was estimated.
Formal 3-sigma X-band uncertainties are below. It would be more realistic to
scale the middle Doppler column up by a factor of 5 (or keep that in mind).

Setups
Plans for the July 6 track
--------------------------
On July 6 we will do bistatic DSS14 -> DSS13 and monostatic observations starting with solution 41.
We plan to use a significant portion of the time to test the digital receivers.
We will begin with bistatic hopped CW observations using the setup below:
