<h1> On-line asteroid identification </h1>
<p> <a href="https://github.com/Bill-Gray/lunar">
Source code for this can be found on GitHub. </a> </p>
<p> This is an on-line version of the <a href="astcheck.htm"> <tt> astcheck
</tt> </a> program used for identifying observations with known objects.
Use the form below to find asteroids that might match the position/motion
of objects you've observed. </p>
<p> Suggested quick start: <b>Don't panic!</b> Copy/paste observations
for one or more objects in the large text window below, <em> or </em>
click on "Browse" to pick a file containing the astrometry. Then click
the "find matching asteroids" button. That will probably be all you
need. </p>
<p> The output will show each object, and its motion in arcseconds/hour.
After that, you'll see possible matching objects, and their offsets in
arcseconds and their motions in arcseconds/hour. You can set a limit for
the search radius, and can tell the program whether to use the Minor
Planet Center's <a href="http://www.minorplanetcenter.org/iau/MPCORB.html">
MPCORB </a> or the Lowell Observatory <a href="ftp://ftp.lowell.edu/pub/elgb/astorb.html">
ASTORB</a> orbit catalog. The latter offers "current ephemeris uncertainty"
data. This is not perhaps as rock-solid as it ought to be, but can tell
you if the predicted position from the orbital elements is very, very good,
or complete rubbish. </p>
<p> You can also show only possible matches with unnumbered objects, useful
to those who are already pretty confident that the object isn't easily identified. </p>
<p> If you're still not getting things to work, contact me at

(modified to baffle spammers). </p>
