Irmintraud (773)



I feel its only fair to the current asteroid search teams to note that Asteroid (773)  Irmintraud   hasn't been "neglected". It has been extensively
observed by the asteroid surveys in 2002. Here are the osculating elements
for it from the Minor Planet Center. To get predictions to compare
with observations to the arc second level, one must use numerical integration
which takes account of all pertubations not an osculated elements
like Guide 7 and Skymap Pro or the Minor Planet ephemeris service use,
they are only meant to locate the object, not analyse it. I also include
the 2002 observation residual listing, which illustrates the accuracies
currently achieved.
