I don't think they would be visible through the eyepiece
this is from the nasa asteroide watch page
(2010 RX30) 2010-Sep-08 0.0017 0.6 9.8 m - 22 m 27.2 10.00 (2010 RF12) 2010-Sep-08 0.0005 0.2 5.8 m - 13 m 28.3 6.01 I don't know how to convert H into visual mag, but they look kind of faint

Seems it has already happened !
At time of closest approach for 2010 RF12 30 (2:12 p.m. PDT ), the asteroid will be approximately 49,088 miles (about 79,000 kilometers) above Antarctica.

2pm PDT Wed is about 4hrs ago !

Please correct me if I have this wrong
I am going to correct the news reports in my weekly NT wide radio spot shortly

I tried to plot it's (RX30) course with elements that weren't so easy to work with.
I used Starry Night. I don't know how accurate I am, but........

By my calc's it was very close to Saturn on Wednesday and climbing. About 2-3 degrees up from Saturn now. Approx same Lat as NGC4437.

Edit: Tuesday the 14th around 6PM, it's coming up right near NGC4691 (approx 3" of separation to the northern side of NGC4697)
If I have the calc's right.
