This just came across the Minor Planet mailing list. I'm going to try for it and thought maybe folks here might want to give it a try too. By the time it gets up in our sky this weekend it should be around +16 which will put it well within reach of many on this list (for imaging, not viewing). Begin forwarded message:
2010 JV34 got pretty heavily pounded right after discovery, no doubt due to its being 16.8V at discovery. Over the next few weeks it's predicted to brighten to 16.0V. For those with the capability, this 400-m PHA may make a good photometric target before it rapidly fades after it;s closest approach.
You can get ephemerides here: http://www.cfa.harvard.edu/iau/MPEph/MPEph.html Where it asks for an observatory code and if you are in N. Utah you can use mine, 718. But you only need to enter that if you want to know where the target is relative to your horizon. If all you want are the RA/Dec the observatory code is not needed. patrick
