2013 NJ Goldstone Radar Observations Planning


Background



2013 NJ was discovered by Pan-STARRS (Haleakala, HI) on July 1, 2013.  
Its physical characteristics are unknown except for its absolute magnitude of 21.8, 
which suggests a diameter within a factor of two of ~140 meters. 

2013 NJ will approach within 0.0063 AU (~2.5 lunar distances) on Nov. 26, but it will be too 
far south for either Goldstone or Arecibo to track at that time.  Shortly afterward 2013 NJ will
move back north into the beam at Goldstone, where we plan to observe it on Nov. 30 and Dec. 1.
We expect it to be a strong target and we hope to image it with 40 MHz (3.75 meter) chirps.

2013 NJ is outside Arecibo's declination window until Dec. 12 when it will be 0.06 AU from
Earth and moving away.  The SNRs at Arecibo will be significantly weaker than at Goldstone
to to the much greater distances, so we haven't scheduled any observations at Arecibo.

2013 NJ  has been classified as a "Potentially Hazardous Asteroid" (PHA) by the IAU's Minor Planet Center.
This asteroid is also on NASA's NHATS list of potential human mission targets.

We would like to thank Joe Pollock and Tyler Linder for reporting astrometry that 
reduced the pointing uncertainties so much that pointing at Goldstone is no longer an issue.

Arecibo SNRs assume Ptx = 900 kW

The SNRs are much weaker at Arecibo so no radar observations there are on the schedule.

Lightcurves reported by Petr Pravec indicate very slow rotation for this object, which
is consistent with the very narrow bandwidths seen in Goldstone data on Nov. 30 and Dec. 1.
Prave estimates that the period is at least 7 days.  Revised SNR estimates are below:

The asteroid will be in the beam as soon as we get the telescope. 


There aren't any tracks scheduled at Arecibo due to the weak SNRs.


Uncertainties

From Jon Giorgin, 2013 Nov. 29:

Now with 50 optical measurements (July 1 to November 28),
2013 NJ orbit solution #20 was estimated.

OSOD with nominal predicts has been updated on aardvark,
including 14v-99-14.s20 variants for the speckle experiment.

From Jon Giorgini, 2013 Nov. 27:

Based on 40 optical measurements spanning 2013-Jul-1 to 2013-Nov-27,
2013 NJ orbit solution #16 was computed. 

OSOD with nominal predicts has been established on aardvark in the
