All,
BY70-1 may be expected to re-enter on February 18 around 01:05 UTC ± 1 hour.
If you wish to track the satellite all the way to the re-entry, I suggest you use the following TLE sets:
After 2017-02-17, 19:00 UTC use this TLE set: BY70-1 180 x 153 km 1 41909U 16083C 17048.79504626 .12181346 12893+0 71409-3 0 99991 2 41909 97.5409 131.9041 0020298 184.6552 175.3259 16.39700464 8178
After 2017-02-17, 20:30 UTC use this TLE set: BY70-1 174 x 150 km 1 41909U 16083C 17048.85604685 .15184949 20755+0 66732-3 0 99998 2 41909 97.5404 131.9770 0018254 184.4013 175.5826 16.41354756 8186
After 2017-02-17, 22:00 UTC use this TLE set: BY70-1 167 x 146 km 1 41909U 16083C 17048.91697788 .20752091 42136+0 63726-3 0 99993 2 41909 97.5397 132.0500 0015727 184.1470 175.8399 16.43503239 8199
After 2017-02-17, 23:30 UTC use this TLE set: BY70-1 156 x 140 km 1 41909U 16083C 17048.97781267 .34949706 12852+1 64507-3 0 99992 2 41909 97.5387 132.1232 0012260 183.8922 176.0983 16.46726667 8207

BY70-1 may be expected to re-enter on February 18 around 01:00 UTC +/- 3 hours.
The apogee of the satellite has now decreased to 242 km and the perigee has decreased to 176 km.

All,
As a result of lower solar activity in the past week, the decay rate of BY70-1 has decreased. The satellite may now be expected to re-enter around February 16 to 19.
The apogee of the satellite has now decreased to 313 km and the perigee has decreased to 191 km.
