Arecibo SNRs assume Ptx = 900 kW and gain = 10 K/Jy.
Consequently, these numbers are optimistic by more than a factor of two.

The asteroid will be more than 20 degrees above the horizon at the start of precal
so we can begin to observe it as soon as we're ready, which could be as much as one hour early.

...We do not know yet if Ryugu will be scheduled at Arecibo due to the cable failure in August 2020...
