(144411) 2004 EW9 Goldstone Radar Observations Planning


Background


(144411) 2004 EW9 was discovered at Palomar by NEAT on March 15, 2004. 
This object is a slow rotator with a 50-hour period, and it has a large lightcurve
amplitude of 0.9 magnitudes that provides strong evidence for an elongated shape.  
Its absolute magnitude of 16.5 suggests a diameter within a factor of two of 1.5 km.

2004 EW9 will approach within 0.12 AU of Earth on July 16, 2012 when it will be
a moderately strong radar target at Goldstone and an excellent radar target at Arecibo. 
Four tracks are scheduled at Goldstone between July 15, 16, 20, and 21 and six
tracks have been scheduled at Arecibo between July 11-15.

Goldstone and Arecibo tracks have been designed to maximize orientational coverage of this object.
We expect to see a bandwidth of few Hz at Goldstone, and due to the inference that this object
is elongated, the bandwidths may vary considerably from day to day.  Due to the slow rotation,
though, the asteroid will rotate less than 35 degrees during our longest track, so during each track
the bandwidths shouldn't change much.

Arecibo detected echoes from this asteroid on July 11 and obtained a bandwidth of about 0.3 Hz.
This suggests that Goldstone echoes could have a bandwidth of about 1 Hz if we see the asteroid
at a similar orientation.

The next opportunity to observe 2004 EW9 with radar is in June of 2020 when it will approach 
within 0.09 AU.

2004 EW9 is a bright optical target (~16 mag) in early June, but then it gets too close to the Sun
and becomes a daytime object until early August.

2004 EW9 will move only 18 degrees between July 11-21 so the subradar latitude should 
change little.


DAILY ROTATIONAL PHASE COVERAGE

This figure shows the maximum rotation phase coverage possible on a given date if everything works and there are no gaps. There have already been significant gaps at Arecibo on July 11 and 12, so Goldstone observations on July 15 and 16 could help fill them.

Uncertainties


From Jon Giorgini, 2012 July 3:

With 1561 optical measurements (2001-Mar-14 to 2012-Jun-7),
144411 (2004 EW9) orbit solution #152 was estimated and OSOD
with nominal predicts established for both Arecibo and DSS-14
in the /a144411 sub-directory.

Setups


Due to the slow rotation, we are expecting a bandwidth of only a few Hz, so 
we're going to start with a CW setup that should produce a quick detection
and resolve the echo in frequency.


CW setup:
---------------------------------------------------------------------------
TX polarization           RCP
RCV polarization          LCP & RCP
Frequency hops:           4                          
Dwell                     30 seconds   
Bandwidth:                4000 Hz 
Sampling interval:        2500 x 0.1 usec
VME FFT for PSD files:    16384 for 0.24 Hz resolution 

Ranging setups:
---------------------------------------------------------------------------
127 x 128 10-usec
baud             10 usec
code            127
PRP            1270 usec
FFT             128   
ncoh              2 
bandwidth       394 Hz   
resolution      3.1 Hz
TXOFF           +50 Hz  (echo in bin 64+16=80)
---------------------------------------------------------------------------
127 x 128 11-usec 
baud             11 usec

bandwidth       358 Hz   
resolution      2.8 Hz
TXOFF           +50 Hz  (echo in bin 64+18=82) 
-------------------------------------------------------------------------
255 x 128 1-usec single sample

code            255
FFT             128

bandwidth       245 Hz   
resolution      1.9 Hz
TXOFF           +30 Hz -> echo would be centered at 64 + 16 = 80
-------------------------------------------------------------------------------
0.25-usec ranging 
baud            0.25 usec
code            255
FFT             256
ncoh            240 
bandwidth       65  Hz     
resolution      0.26 Hz
TXOFF          +10 Hz -> echo would be centered at 128 + 39 = 167
