Daniel Deak posted the following elset: LRE 1 26898U 01038A 03278.40931975 -.00025728 -13639-6 -10673-2 0 3834 2 26898 27.9429 198.9853 7300229 272.9474 322.9372 2.29452697 17405 This elset is now almost 30 days old and I assume that a negative drag term indicates a mistake has been made. Previous elsets: 1 26898U 01038A 03268.88970653 .00006578 -72886-6 20125-3 0 3799 2 26898 27.9535 202.6552 7301752 267.0624 15.6413 2.29513641 17180 1 26898U 01038A 03272.80957775 .00005348 -44947-6 18064-3 0 3819 2 26898 27.9495 201.1390 7300721 269.5041 14.7283 2.29551499 17272 The perigee is in the southern hemisphere and the drag term is non-zero. The drag term has increased from 0.000007 in January to 0.000060 in the above elset. The "int2" program indicates that the perigee height would subsequently increase from 178 Km back up to 215 Km at present, so the drag should be down to about 0.000030 at present. I would assume that an incorrect obs was used to generate an elset with a negative drag term and that subsequent attempts by Spacecom to find this object using an erroneous elset have failed and will fail in the future. Is anyone with a CCD system that can reach 14th magnitude interested in performing a one hour search in the evening sky? Has anyone ever seen this object?
