A NEO called 2013 XY8 is closing on Earth and the folks at Goldstone are asking for amateurs to get astrometry on it tonight so they'll know more precisely where it is when they try to hit it with radar. It's to be well placed for we in Utah tonight and pretty bright at magnitude 15ish. Note the speed across the sky increasing tonight from 45 arc seconds per minute to nearly 70 so short exposures will probably be needed to keep the target from trailing. If anyone on the list gets some good images tonight please let me know and I'll help with measuring and submitting. Here is a cut and paste from the Minor Planet Ephemeris Service showing hourly positions as calculated for my observatory. For more precise ephemerides for other locations go to http://www.minorplanetcenter.org/iau/MPEph/MPEph.html and enter "2013 XY8" in the object box and your long/lat/alt where indicated.
