Background


(308242) 2005 GO21 was discovered by the Siding Spring Survey on April 1, 2005. 
Not much is known about this object, except that its absolute magnitude of 16.4 suggests a diameter of ~1.6 km 
(within a factor of two).  On June 12 we learned that David Higgins recently obtained lightcurves
that yield a period of either 5.5 h or 11 h, so we have updated the SNR estimates below to reflect this. 
All else being equal, the SNRs will be stronger than we originally guessed.

Note added on June 18: Goldstone images on June 17 suggest that the rotation period is about 11 hours.

2005 GO21 will encounter Earth at ~21 lunar distances (0.0439 AU) on June 21. 
This is its closest approach until June of 2029 when the asteroid will be at a similar distance from Earth.

2005 GO21 will be an excellent radar target at Goldstone and an outstanding radar target at Arecibo. 
With the new information about the rotation period, we expect bandwidths of about 15-30 Hz.

There are five monostatic tracks scheduled at DSS-14 between June 16-25.  After we realized that the SNRs will
be stronger than originally anticipated, we added two tracks at DSS-13 to receive Arecibo transmissions on 
June 22 and 24.  Monostatic observations at DSS-14 are also on the schedule on June 22, so on that date we'll
observe with both DSS-14 and DSS-13, but record data separately.  Arecibo observations are scheduled
from June 22-26.

We are expecting signal-to-noise ratios sufficiently strong for observations with the chirp system at resolutions
as fine as 0.05 usec (7.5 meters) and perhaps even 0.025 usec (3.75 meters).  At Arecibo, 2005 GO21 should be 
strong enough for imaging at 0.05 usec (7.5 m), which is the finest range resolution available at that telescope.

2005 GO21 is a 15th magnitude object in early June and about 80 deg from the Sun, but by the middle of 
the month it will be too close to the Sun for optical observations.

2005 GO21 has been classified as a "Potentially Hazardous Asteroid" by the Minor Planet Center.

#3) DSS-14 predicts

 PRDX.OUT.14f-14-14.s47 (DSS-14 monostatic; xmit at constant 8560 MHz)
 PRDX.OUT.14v-14-14.s47 (DSS-14 monostatic; xmt variable, rcv at 8560 MHz)

Someone had created a file "PRDX.OUT.01f-01-01.s47" in the DSS-14 aardvark
directory; not sure of purpose, but it used an X-band reference frequency 
for Arecibo (8560 MHz constant). So I re-did it at S-band and the file
is now "Arecibo xmit at constant 2380 MHz", though still in Goldstone 
format.

From Jon Giorgini, 2012 Jun 11:

Including 122 optical measurements (2005-Apr-1 to 2012-Apr-30),
308242 (2005 G021) orbit solution #37 was estimated and OSOD with 
nominal radar predicts established in the /a308242 sub-directories
for both Arecibo and DSS-14.

Setups



Plans for June 23: 

We will start with solution 49. 

MONOSTATIC OBSERVATIONS AT DSS14:  We'll start with the CW setup below, do 5 runs, estimate a Doppler
correction if needed (which is unlikely), do a couple of 1 microsecond runs, and then
devote the rest of the track to 40 MHz (3.75 meter) imaging with the chirp system using
the same configuration we used on June 22 (40 usec PRP).


BISTATIC ARECIBO/DSS-13 OBSERVATIONS:  We don't have any Arecibo/DSS-13 observations on June 23, but
we have another track on June 24.  On June 24 we'll use solution 47 again and receive from 
1550-1608 and again from 1820-1836.  This is at 2380 MHz (S-band).  Lance or Michael will
monitor logs at Arecibo to coordinate observations at DSS-13.
