2013 BS45 Goldstone Radar Observations Planning


Background


2013 BS45 was discovered by Spacewatch on January 20, 2013.  The physical 
properties of this object are unknown other than its absolute magnitude 
of 25.7 which suggests a diameter within a factor of two of 23 meters.  

This object is on the "NHATS" list of potential human mission targets, so there's considerable 
interest in improving its orbit and understanding its physical properties. 

2013 BS45 will approach within 0.0123 AU (4.8 lunar distances) on Feb. 12.  We're 
going to observe it during time already scheduled for Camillo on Feb. 10-13 when the SNRs
should be sufficient to get a detection.

Uncertainties

From Jon Giorgini, 2013 Feb 12:

Marina sorted out the ambiguity with the 2013 BS45 delays
and updated to orbit solution #22. This has radically reduced
the uncertainties:

Setups


We're going to start with the CW setup below.  We know nothing about the rotation period,
so we'll start with a standard setup in the hope that it will resolve
the object.

Due to the very short round-trip time, we will NOT hop the transmitter.



TX polarization           RCP
RCV polarization          LCP & RCP
Frequency hops:           no hops
Bandwidth:                4000 Hz 
Sampling interval:        2500 x 0.1 usec
VME FFT for PSD files:    256 for 0.15.6Hz resolution
