Granat                                           203238 x 211 km
1 20352U 89096A   99141.75000000  .00000000  00000-0  00000-0 0  9158
2 20352  48.7873 283.4465 9390426  21.8293 352.6408  0.24428860 11724

was still the latest elset on June 1 (99152).
It was predicted to make a perigee pass over Saudi-Arabia at 00:21 on May 30, and decay there, according to NPOE30. Mike's INT2 puts the decay at the next perigee over Africa 990603 at 02:40 (?)

If it barely survived the May30 perigee, it could have returned for decay at 02:01, but only visible from SE Europe.

No other decayers from Alan's decayers May 24-June 04 were close to W.Europe, and within +/- 30 minutes.
SeaSat debris 25055 was over Hungary 01:05, and Spain-Ireland on the next orbit.
NB: I used the dklist.tle on May 31, so maybe a real decayer was already removed !!

If Granat is still up, its decay could be seen from Libya, Crete, Greece, Turkey, Cyprus...
around 02:40 UT tonight
