I generated an ephemeris for 2100mst 2 July - 0430 3 July with the
topocentric RA & Dec. This was done using my house in northern Glendale =
as
the position. I have it in an excel file if your browser messes up the
columns. Email me off list & I'll send it to you.=20

Subject: [AZ-Observing] 2004 XP14 close approach
This is a head's up to mention that the asteroid 2004 XP14 will be
passing close to Earth in the coming days. It will become as bright as =
mag
11 for several hours centered at about 10h UT for July 3.
It will be in the far northern Milky Way moving at several arcseconds =
per
time-second, so ought to be readily distinguishable in a medium sized
telescope.
Because of the close approach, you'll have to get topocentric
ephemerides for some location near you (meaning within a few thousand km
radius on Earth). Among the choices for such are the Minor Planet =
Center's
own site:
http://cfa-www.harvard.edu/iau/MPEph/MPEph.html
...which allows input of long/lat as well as observatory codes, or the
Lowell one:
http://asteroid.lowell.edu/cgi-bin/koehn/asteph
...which shows a list of locations of observatory codes.
You can also try the JPL site for the object:
http://neo.jpl.nasa.gov/cgi-bin/db_shm?sstr=3D2004XP14
...which has links to generate an ephemeris. The default geocentric
ephemeris will not be good enough to find it, however.
