The following is based on Brad Young's precise observations of last night, and precise, but less complete information
from a different observer hours earlier:

1 70001U          14225.09108567  .00035829  00000-0  15546-3 0    02
2 70001  43.5037 146.0255 0004000 249.2218 110.7629 15.83804024    08

The orbit could conceivably be a bit higher in altitude, so it could run somewhat later than predicted by the above, but
probably not much later than given by the following:

1 70002U          14225.09112572  .00034123  00000-0  15546-3 0    00
2 70002  43.5037 146.0362 0009660   5.0429 355.0547 15.82776287    08

RAAN and especially eccentricity and argument of perigee lack precision, so expect track errors of at least half a
degree.

Barring further manoeuvres, a few more precise observations tonight will yield reliable elements.

Due to other commitments, I may not be able to respond promptly to reports that arrive between about 18:00 and 01:00
UTC.
