Tonight, the LCROSS satellite will pass between Cor Caroli (alf CvN) and M94 (for my o.p. at W110 N41) at around 7UT 2009.  Because there are no USPCMD two-line elements,topocentric plots can be generated using the NASA JPL Horizons emphermis generator. http://ssd.jpl.nasa.gov/horizons.cgi It is uncertain whether the satellite will be too faint to image. Use 15 mags for image exposure planning. See chart at: http://members.csolutions.net/fisherka/astronote/observed/LCROSS/CruiseFinde... in http://canopus56.wikispaces.com/LCROSS_Cruise_Orbit I notice that LCROSS at around 466,000km, unlike most lower fast moving satellites, has an parallax "hump" in its daily orbital path.  This appears to be related to realitively slow orbital movement of the satellite each night. The relative change of the observer on the Earth's rotating surface generates a slight parallax movement.
