After a low pass at 03:31, I get an error from Skymap about ndot or drag being too large. I was not able to use the elsets in STSPLUS due to similar problems. Granted the object may not be in orbit after 331 UT (17 Mar), but I would like to observe it again if possible. Is there another program that will work with elset or should I wait for an elset with a lower drag term that is acceptable to Skymap? This is an interesting object. Alan's comment about the object being lower if earlier ( higher if later ) was right on. Will have to visualize the orbit to understand the viewing changes. But it makes future obs of this nature easier to undertake since I will be able to make adjustments for likely elset uncertainties. Is the earlier/lower, later/higher adjustment for near apogee objects a general rule, or might that be reversed under different conditions? Ron Lee
