OIG have issued three elsets for the abortive Mars 96 launch:

Mars 96                                          180 x 119

Taking the second of these elsets, SatEvo predicts decay at November
17.7 (within the next hour as I post this). The third elset (on which
the following SatEvo predicted elsets are based) leads to decay at about
November 18.2:
