Hi Charles,

If I fit a circular orbit I get:

OBJ
1 99999U          26027.06766949  .00000000  00000-0  50000-4 0    01
2 99999  49.9938 268.3992 0001000   0.0000 132.5304 13.76398385    00
# 20260127.07-20260127.07, 4 measurements, 0.007 deg rms

The 50 degree inclination matches the HULIANWANG DIGUI constellation, but I can't find an exact match.
Fitting the RAAN and Mean Motion shows it is similar to:

0 HULIANWANG DIGUI-139
1 67437U 26007C   26034.48971301  .00000017  00000-0  15331-3 0  9994
2 67437  50.0436 211.7557 0007150 298.1028  61.9144 13.79550163  2904

I would assume it is a fresh one of these.

Best regards,

Eelke.
