Background


This is a planning page for FOUR near-Earth asteroids scheduled for radar observations at
Goldstone between August 21 - 27, 2013.  Here are the dates when observations
are scheduled for each object:

           Goldstone                   Arecibo            First         Goldstone expectations
1998 ML14  Aug. 21, 24, 25, 26         Aug. 28-Sep. 2     Goldstone     Hi-res imaging
1999 CF9   Aug. 21, 22, 23, 24, 25     Aug. 16-21         Arecibo       Lo-res imaging
2004 AR1   Aug. 26                     Aug. 31-Sep. 2     Goldstone     Weak; astrometry
2007 CN26  Aug. 25, 27                 Aug. 28-Sep. 2     Goldstone     Lo-res imaging

The detailed schedules appear below.

Of these objects, 1998 ML14, 1999 CF9, and 2007 CN26 should be strong enough for imaging.  2004 AR1
should be much weaker and is unlikely to be an imaging target, although lightcurves obtained
by Joe Pollock at PROMPT show that the period is clearly longer than 4 hours and that the lightcurve
amplitude exceeds 0.6 magnitudes.  As such, 2004 AR1 may be a much stronger radar target than 
expected and it seems very likely to have an elongated shape.  1998 ML14 will probably be the
strongest target and we hope to image it at 7.5 meter resolution with the chirp system.  During
the observations, Mike Hicks reported a rotation period of 6.5 h for 1999 CF9 based on photometry
obtained at Table Mountain Observatory.

This is one of the most intense near-Earth asteroid observing schedules we've ever attempted at
Goldstone, and if it turns out that any of these objects are significantly weaker than expected,
we may cancel tracks to alleviate the load on everyone.  However, we observed 1998 ML14 with radar
shortly after its discovery and we _know_ it'll be a strong target.


The table below gives the discovery date, telescope, close approach distance and date, orbital parameters,
and physical properties for each object.  All four objects are classified as potentially hazardous.

A lightcurve obtained by Joe Pollock indicates that the rotation period of 1994 AR1 is
significantly longer than 4 hours, so the SNRs may be stronger than shown above.

On August 28 and 29, we hope to do radar speckle observations of 1998 ML14 using transmissions at Arecibo
and reception of echoes with the VLBA stations at Pie Town, Los Alamos, Kitt Peak, and Ford Davis.
We requested 20 minutes on each day.  (Michael Busch, PI)

Setups



For the first track, here's a CW setup for 1998 ML14.  We're expecting a bandwidth of about 6 Hz.
This should produce a quick detection and resolve the object in Doppler frequency.
