2012 MY2 Goldstone Radar Observations Planning


Background


2012 MY2 was discovered by the Mt. Lemmon Survey on June 19, 2012.
Nothing is known about this object, except that its absolute magnitude of 26.3 suggests that it's a tiny
object roughly 20 meters in diameter.  However, it's possible that the rotation period and spectral class
may become available shortly before we observe this object with radar.

Update on June 28: Patrick Wiggins reports that this object appears to be a rapid rotator with
a possible period of only several minutes.

2012 MY2 will encounter Earth at 1.3 lunar distances (0.0035 AU) on June 29. It should be a strong radar target
and we hope to image it with the chirp system at its highest resolution of 3.75 meters. 

We have two tracks scheduled at Goldstone on June 30 and July 1.  Due to the very short round-trip travel times,
both tracks will be bistatic and we'll use DSS-13 as a receiver.

On July 1 we will also devote 30 minutes to radar speckle tracking observations in collaboration 
with Michael Busch.  We will transmit fixed frequency to the geocenter and receive echoes at DSS-13 and the
25-meter Very Long Baseline Array antennas at Owens Valley (CA), Kitt Peak (AZ), Los Alamos (NM), 
Pie Town (NM), and Fort Davis (TX).  If successful, these observations will enable us to estimate the 
asteroid's spin state.  These will be ** X-band ** observations, unlike the recent Arecibo/DSS-13 S-band
observations of 2005 GO21.

As of 2012 June 26, 2012 MY2 is an 18th magnitude object and is rapidly approaching the Sun.  Physical observations 
and astrometry might be possible until about June 30th.

2012 MY2 has an unusually accessible orbit relative to Earth's with a delta-V for a rendezvous that is among
the lowest currently known.  This asteroid has been appeared on NASA's official
list of objects being considered for future robotic and human exploration missions (http://neo.jpl.nasa.gov/nhats/).

The track on DOY 183 immediately precedes a Mercury/GBT radar speckle displacement track, and we plan to transmit 
for 30 minutes into what would have been the precal time for Mercury.  That will still provide _plenty_ of time to 
prepare for the Mercury observations.

NOTE: TXON is shown at the earliest time, which is only 15 min into the precal time on both dates

Uncertainties


From Jon Giorgini, 2012 June 29:

Including the just e-mailed data, which extended the data-arc
(132 optical measurements, Jun 19-29.3 2012), 2012 MY2 orbit solution 
#14 was estimated and the predict files on aardvark updated:

In light of the new astrometry, some prior data was reweighted for s14. 

The suspected bias now shouldn't be an issue and the above s14 statistical 
uncertainties should be realistic. 

Continuing our prediction difference table:

 -1636 usec, +40.053 Hz, 31.6 arcsec change

s11-s09:

... so the s11 update was indeed inconsistent, with s14 being closer
to the "original" s9:  ~1.5 sigma update instead of 2.3.
