The flashes that I observed were, upon further review, probably
closer to +6.   The Globalstar UNID was brighter by
comparison.  At any rate they were easy to spot against the

Same as my obs.

FWIW I had asked NASDA about the spin rate of MDS-1.  This was
the response:
With regard to Spin rate of MDS-1, the answer you asked about is
the followings.

MDS-1, called "Tsubasa", rotates around Z axis by 5 rpm (rotates once
every 12 seconds).
Tsubasa dosen't rotate Sollar Arrey Panel (SAP). Tsubasa rotates itself
aquisitioning the SAP to the sun.

Tonight at my location MDS-1 and 90012 appear to pass along the same track, about 7 minutes (2 to 3 deg of azimuth) apart.   It
should be interesting to see if MDS-1 has a surface that will
flash at 12 second intervals and 90012 flashing at 8 second

Has anyone observed MDS-1?
